Deizens of the Saltwater Tank

Despite having added only live rock and snails, the 5 gallon hex tank is showing an amazing amount of macro biodiversity.  This is a short post to document what is growing in there!

A multitude of dwarf cerith snails

These guys are the workhorse of the algae fighting army.  There are many of them, in many shapes and a variety of sizes.  They like to crawl up and down the sides of the tank, and will occasionally congregate there.  Sometimes they hitch a ride on the back of larger snails!

This big guy is a florida cerith!

If I had to pick the coolest looking species of snail in the tank, it would be the Florida cerith.  Between their green coloration and rippled shell, they are hard to beat!  Not to mention these snails can self-right themselves!  These are are the largest snails in the tank.

This is the nassarius snail, in the middle. it looks like he is hitching a ride on a Florida cerith

If you zoom in you can tell this is a nassarius on a florida cerith snail.  The nassarius is easily distinguished by its single long stalk that probes for algae.  These guys are speedy!

Heres a nerite snail

My nerites are identifiable by the deep grooves that run along their round shells.  they have two long feelers, unlike the nassarius.  These guys are also very speedy.  Here, the nerite is harassing a dwarf cerith.

This is a featherduster

This guy was quite the find! It came as a hitchhiker on some live rock I bought.  It seems to have grown some since the rock was introduced, and it certainly is less skittish now.  there is another one on the same rock with a green/purple coloration, but it is hard to get a picture of that one because it is shy and very well hidden.

Cyanobacteria!

I thought this stuff was algae, but I was wrong!  It turns out to be purple cyanobacteria.  Its HUGE, and the snails seem to nibble at it from time to time.  I really don’t mind it, although it is considered a pest.

Thats all for now!  Maybe I will notice more stuff as time goes on.

 

 

Adventure: Dawn Mine at Dusk

You can’t tell, but there is an underground waterfall behind us.

After the Kelsey mine trek, I expected my adventure to Dawn mine to be a light hike, followed by the exploration of a small mine.  It is in the well hiked Millard Canyon, just outside of the suburbs surrounding LA to the north.  It is not even a long hike- the trip report I found here pegs it at a 5 miles round trip.  This was supposed to be a trip to test the mettle of a new potential adventurer, Chloe, for a canceled adventure to the Allison mine.

View of LA from Millard cyn Trail

The team this time was Chloe, the ever-reliable Hardee, and myself.  We began the adventure by purchasing an ANF adventure parking pass at Turners, and heading up lake street to Millard Canyon.  Upon arrival, at about 3:00 PM, the car had some trouble turning off its engine, but once that was sorted we started our hike by heading out on the East road from the first parking lot.  This led us along the crest of a hill that offered superb views of LA and the surrounding cities.  We followed this path and it wrapped around a hill to our right and descended into the valley floor.  Once we hit the rangers cabin, we descended into the river bed and the adventure began in earnest.  We were careful to take note of and remember warning sign that was posted on a large tree in the river bed near the cabin; this would be a waypoint for us on the way back, in case we did not see the cabin.

The Falls!

We continued up the rocky riverbed until we hit a fork.  A high path that looked like a river bank led off to the left, while the other plunged back down into the bed and continued up a rocky tributary.  We decided to go left here and visit Saucer Canyon Falls, which were nice.  We saw some people who had climbed up pretty high. We will definitely be back to climb up them someday!

Captain Crazypants leads the way

Before we returned to the main path, we met a dog (we assumed it belonged to the folks who were up on the falls), who we nicknamed capt. Crazypants.  Hardee had some jerky on him, and the dog would not leave him alone!  As we left, the captain followed us.  At first, we hoped he would go back to his owners, but it quickly became clear that he was leading us to the mine, and not the other way around.  There were also a lot of spray-painted arrows that went in the direction of the mine.

Hardee gets ready to traverse some rocks. Note arrows

We continued up the rocky streamed, doing our best to follow the instructions on Dans hiking pages.  We were looking, in particular for the point where “If you miss the trail you’ll find yourself climbing over and through the granite maze until the massive rocks forbid you to climb any further”.  Fortunately, we never found it and continued up the trail mostly through the riverbed, trying to skirt around spots of still or flowing water, and trying to stick to the more easily traversable river banks.

The captain going the wrong way.

By the time we got past these rocks, we were pretty tired, and the sun was starting to set.  We increased our pace, but our minds were wearied by the unknown length of the road ahead.  Captain Crazypants helped keep our spirits aloft, and kept leading the way.  The sun started to set as we entered a forested portion of the streambed.

We were concerned about the sun going down, but we pressed on and eventually found the lower entrance to the mine.  There were many false-positives along the way, but the remains of some kind of steam engine give away the path to the entrance.

Large beams and steam engine on the way to the entrance.  Crazypants is still doggedly leading the way.

More spraypaint indicates exactly where the entrance is, hidden behind a boulder

Once at the entrance, we did a quick check of our lighting equipment.  I personally regret that we only had one light/person.  It just goes to show you that you always need to be over-prepared, even for hikes that seem like they should be easy.  The entrance was flooded, so Hardee and I switched to fivefingers and flip-flops (respectively) and Chloe decided to brave it in her shoes.  As we scouted out the entrance, Crazypants balked at the idea of even getting close to the entrance, and ran off, never to be seen (by us) again.  We miss you Crazypants.

Flooded entrance. Note the hinge on the frame.

As we made our way in, we noticed a lot of wood in the entrance.  I was originally concerned, as it looked like shoring, which would indicate that the miners thought it was unstable.  I breathed a sigh of relief when I looked a little closer and realized that the tops of the posts were not touching anything, and that there were heavily corroded hinges in the frame.  It looked like a gate that had been installed and removed some time ago, according to the LA goldmines website.

It turns out you can make it past the entryway and into the mine proper by carefully walking on the partially submerged wooden beams in entry; the caveat is that they sometimes move, but we were careful and managed to get over them dryly.

Possible passage to an upper level, from the ceiling of the first level.

The first floor of the mine today consists of two main tunnels branching out from the vaulted ceiling directly after the entry.  There are stories and maps of an upper level, but we did not have the time or equipment to explore that area, although we did see passages leading upwards.

To the left, there is a long, rather echo-y passage with several alcoves along its length.  By the time we reached the end of the winding passage, we were proceeding at a brisk walk.  It may have been the underground waterfall in the distance, but I felt like I heard a low rumble as we walked along, and that scared me.  After turning around, we observed a short moment of darkness where we all turned off our lights.  This did not last long, as the darkness is terrifying, and Chloe decided it was time for lights again.

The PIT.

After reaching the main area again, we set out to explore the other passage.  To do this, we had to navigate a thin ledge on the edge of a huge pool of water,  reputed to be 55-80 feet deep.  Scary, and very full of very cold water.  I hypothesize that it was originally another mineshaft, but later they ran into water and it flooded.  Someday, somebody should build an ROV and see what there is to see down there!  Hmm.  Somebody interested in mines, who is an engineer would be perfect for this project!

The way is not shut, but it is certainly wet!

The source of the water

After not falling into the water, we were rewarded with a sort walk to one of the most amazing things I have seen; an underground waterall.  It is pretty clear here that there was a dam built to prevent flooding of all the tunnels when somebody started tunneling up, and hit some kind of aquifer or spring.  This flooded the rest of the tunnel ahead and up-stream of the dam, which we decided not to explore because the water was VERY COLD.  Instead, we gawked at the waterfall, and took pictures of ourselves.

Chloe managing to not get wet.

With the obligatory MySpace photos out of the way, we continued to be amazing and not fall into the pit of frigid water.  We crept back to the main room and carefully exfiltrated the mine, again being careful not to get wet.  Once outside, we changed back to our normal shoes, had a swig or two of water, and snacked a bit.  It was really dusk in the canyon now, and we began our retreat with our flashlights on, proceeding at a safe, comfortable pace.  I was somewhat unsettled by the prospect of a night hike, but there were really no other options.

Socks! Socks! Socks!  Smartwool socks are the BEST!

Suddenly, it was very dark.  Here Chloe is illuminated in a small pool of light from her flashlight, and Hardee can be recognized by his headlamp.

The rest of the trip was spent in darkness, with the only illumination being that from our headlights, as the dim glow of the moon did not penetrate well into the bottom of the canyon.  It is amazing how big the canyon felt in the darkness.

Watch out for drops!

Chloe Points out some especially treacherous parts of the trail.

After many stream crossings, sort climbs down boulders, and a few instances of tripping and almost falling, we arrived back at the fork.  Here we proceeded to climb about 6 feet back up to the riverbank, and headed back to where we had come from.  Upon finding the marked tree and the steep slope next to the cabin, we ascended out of the canyon floor and back onto the trail.  Feeling that we were almost done, we increased our pace, especially when we noticed a pair of glowing eyes on the cliff above us.

Los Angeles at night.

Just before returning to the car, we cleared the canyon that had been obstructing our view of the glittering lights of the Los Angeles basin.  It was truly a fitting end to the adventure to rise out of the darkness and be reminded that the lights of civilization were still burning strong.  After appreciating this for a moment, we headed in the home-hat direction.

Adventure: Kelsey Mine, Part II (In which we actually find The Kelsey)

The author crawling out of the bottom passage. Success!

My final trip to the Kelsey mine with Hardee and my brother was successful.  There were several reasons for this:

  • Time.  We started out around 9am and did not return to the car until sunset, around 5pm.  We had barely enough time, and you can never have too much daylight.  START EARLY.
  • Equipment.  We had good hiking clothes, good shoes, water, snacks, spare socks, LOTS OF LIGHTS*, and a medium sized knife for cutting away those spiky vines.  We also had a first aid kit.

*You can never, ever have too many flashlights in a mine.  It is 100% dark in a mine, and the small pool of light created by a flashlight is your only way to navigate, unless you are a bat.  I like to bring an headlight and several flashlights with me, just in case.

Some equipment was unnecessary and only slowed us down.  My brother insisted on bringing a huge stack of rope (of unknown origin) and assorted other 30 year old climbing equipment JUST IN CASE.  You know, because it is safer to rap down a waterfall with no training than to just climb back down.  The only real use for this rope was zip-lining his bag-o-crap down the falls so he didn’t fall down carrying it.

Spiky bushes- watch out!

The major hazards encountered en route to the mine were poison oak, thorny bushes, spiky plants, several very dramatically thin trails with large falls where the truck road appears to have been washed out, and several very unstable creek banks that had to be climbed on.  Hazards inside of the mine include a large, ~3 foot deep pit that that can easily be avoided, and a very steep shaft that leads down to two low crawls, as well as very cold water, LOW CEILINGS and possibly some kind of rotting vegetative mass.

We traveled up silver fish truck road until there was a sharp bend to the left, and then dropped into stream bed to our right.  The soil here on the descent was decently packed, and we eventually got to the bottom.  There were signs of habitation or camping in this area, but from a long time ago.  We headed downstream, until it was possible to clamber up on the opposite bank.  The top of the opposite bank had an old mattress on it.  I can’t imagine hauling that up there; maybe it was back in the days of the truck road.  From the opposite bank we could hear water, and we descended the opposite side of the bank to a flowing stream.  This, I believe, was water canyon.  We crossed the stream here, and continued to trek upstream for quite a while.  The going was slow and involved many steep and unstable creek sides, thorny bushes, and possibly poison oak.  Eventually we arrived at the first waterfall.  The remains of an old wooden ladder are here; we are unsure of who constructed it.

Hardee climbs the first waterfall.

 

Here began the waterfall climbing.  There are three falls to need to climb to get to the mine.  You definitely want to keep to the left side of the canyon as you head upstream, because it does branch once and the right fork is not the right way to go!  I suspected that we had reached the mine when the next waterfall was too tall to comfortably climb, and there was large, loose talus, possibly made of mine tailings, to our right (we were headed upstream).

The view from the top of the second falls. The steep, narrow path on the left of the photo appears to be cut out of the rock, and was our ascent route.

After scrambling up the talus, I found the very obvious mine entrance.  There was another entrance or possibly an exploratory tunnel nearby; it did not appear to go anywhere.  The entrance was typically too short for me to stand up in, dark, and unsurprisingly dry, probably due to its elevation above the creek.  After donning our headlamps, grabbing our torches and our map, we were set to enter the mine.  As always, we left our non-essential equipment outside, so we wouldn’t loose it in the mine.

Sign posted outside of the enterance. Ought to say “MINERS MUST BE THIS TALL TO RIDE THE ORE CART”. Watch your head!

The mine is pleasantly complex, with two levels, a steep shaft, several branches, a high ceiling or two.  Unfortunately there was a lot of litter and graffiti, Compared to what I normally see.  Judging by the (empty) case of bud, the giant neon orange “420”, and the numerous beer bottles, there has been at least one party there.  This was surprising, because of how difficult it was to get to.  Maybe this was not always the case, or maybe there were more ladders in the past.  I think the most fun part of the mine is the lower level.  I got a little claustrophobic, but it was magical to crawl through a low passage and discover a flooded passage, full of freezing, crystal clear water, inside of a mountain.

The flooded passage. Difficult to photograph, but very beautiful.

Another cool thing we saw were some copper-bearing minerals or veins.  Here is a picture:

Coppery things!

After exploring the mine, we exited and had a mini-crisis where my brother could not find his phone.  This is why we designate an official camera person, and leave non-essential stuff outside of the mine.  After searching his bags, he couldn’t find it, so back into the mine we went!  Of course, it turned out to be in his bag.  Oh well.  It was still awesome to see the warm glow of sunlight on sycamore leaves as we exited for a second time.

Sunlight never looked so good.

We trekked out the same way we came in, making sure that we reached the trail before the sun started to go down.  I would recommend this trip, as it is full of awesome adventure, and amazing environments.  There are high, exposed chaparrals, a beautiful sycamore forest, a cool, breezy creek bed, waterfalls, and even an old mine to climb and explore!  What more could you ask for?

Adventure: Kelsey Mine, Part I (In which we execute a near-fruitless search)

I may be addicted to adventure.  There is really nothing like tramping out into the mountains, dropping off the beaten trail, climbing up some waterfalls, and then dropping down into an abandoned mine.  I even have an adventure hat, which is mostly silly, but does do the job of swatting away bugs, and keeping the sun out of my eyes.

Every now and then I do realize that adventuring can be scary, and you can really die, but I figure I have to make stories now before I get too old and feeble to get out and do Dumb Things.

My latest Adventure was finding and exploring the Kelsey Mine.  Lost not-so-deep in the Angeles National Forest, it took a whopping three trips to find it.  The first trip was with my friends Katelyn and Rachel, on may 31, 2011.  We took a wrong turn, as you can see on this map:

As you can see, we are not even close to “kind of where we are supposed to be”

We also heard a LOT of rattles in the bushes, which caused us to hasten our return to our vehicle.

The next two attempts were done in late 2011, over Thanksgiving break.  The first one was with Sam and my brother.  We followed the road (silver fish truck trail) on that map until the sharp leftward bend, where we dropped down into what I assume is water canyon. Exploring this involved a lot of crawling up and down through brush, thorny bushes, and spiky vines.  We found a small waterfall, downstream, and a lot of little yellow and brown newt looking things.  After forcing ourselves through a hole in the brush, the upstream route eventually yielded to the floor of a very cool, damp ravine.  The ground was covered in the usual leaf decomposition and dirt detritus.  We made our way up this canyon for maybe another quarter mile, and then decided to turn back on two counts:

  • We found out there were still ticks.  I think Sam got one.
  • Sam had to be home.

Disappointed in our feeble effort to find the mine, I decided to put together another group and go at it again.  Since Sam was busy, and Hardee was not, our party consisted of my brother, Hardee, and I.  Hardee and I have been on a few adventures like this in the past, and I knew I could rely on him.  My brother thinks he knows everything, and can be more than a little cocky, but he is a good climber.  We once again set off to ANF!

This trip was far more successful, and we actually found the mine.  You can read all about how to find it here (Note: we never found the water tower described).  I will probably not post explicit instructions, or detailed topos here, because part of the fun is finding the mine, and if there were spoilers everywhere it would be no fun.  But If you want to read a trip report, with some hints in it, look out for Kelsey Mine, Part II (In which we actually find the mine).

The time is Now!

This blog is mostly to document my projects.  I am a second-year engineering student at The F. W. Olin College of Engineering.  I do projects ranging from biology, to mechanical systems, to embedded microcontrollers.

The name of this blog comes from a philosophy that the time to start projects is not when you have free time, or some weekend when you can squeeze them in, but NOW.  I encourage you to find something cool to build, drop everything for a few hours, and get working.  This blog will hopefully inspire you to do something cool/useful/fun that you would normally not do.
