Disappearing Stream Video



So I'll have to do some more snooping around with this stream. It seems to be getting bigger every year, and I am yet to figure out exactly where this particular stream is discharging into the river (if it is, even).

Science Caught in the Act - Dam Break

I threw this video together earlier today. This is another of a series of videos from "The Station", a first order drainage in which I conduct fluvial experiments. In this case I have released a plug from underneath a dam (fallen log across the stream) and record what happens with the stream afterward.

Enjoy.

Things to get Downright Fluvial About

After a few days, I went through the videos of the drainage experiments, and here they are:
**As of 3/23/2010 17:18, Two of the three videos have not yet been processed by YouTube. Please be patient, they'll be up soon.

#1 - Quick Mass Movement



#2 - Mass Movement and Damming



#3 - Earth Dam Break + Knickpoint Migration



I left out the best part. I ripped some leaves away from around a groundwater seep and watched a beautiful drainage pattern form. However, as soon as I calmed down from the beauty of it all, I clicked the camera on to get a blinking battery icon.

These things happen. I was able to snap a good amount of photographs of it though, and they should be up within a few days.

Also, look forward to this blog linking up with my flickr account within the next few days.

Colorado Springs - Mesa Verde


...is pretty much just a westward trek through the Rockies in southern Colorado. Now, before you hardcore Rockies enthusiasts come at me for that last statement, mind you: we were just passing through at this point on our way to Mesa Verde National Park. If it were up to me, I would have checked out the Tepee Buttes, Spanish peaks, anything and everything between Colorado City and Durango - but it wasn't up to me.

BUT - we stopped by Great Sand Dunes National Park.

I enjoyed Sand Dunes. We actually skipped a stop further in towards Silverton, Colorado, a town built within an ancient caldera to go there. Now, we ended up skipping a few spots on this trip, and I don't know who's to blame for this, so I'll let it go. But please, never tell a group of geologist that they're going to a caldera - and not do it.

On to Sand Dunes. Sadly, we did not spend an ample amount of time here either, but what we did see was what gets geomorphologists like myself to sleep at night.

The first photo on the top of the page, is being described in the lecture of the century by Dr. Albanese here (heavy, dark minerals [magnetite] are being deposited in the shallow stream, due to their higher density, they form bars). I figured that this was about as good as a geology lecture photo gets, so here it is:

What are, I believe, some SUCO field trip goers:
Some serious cumulnimbi forming north of the Dunes:

And later that day...

We also drove over the continental divide, did some nalgene experiments (to no avail) and had a beautiful overlook of the San Juan National Forest later on. At this point, though, we had driven into more storms associated with the thunderheads in picture #4, so photography increased in difficulty.

The Continental Divide (someone put a sign in front of it...):

And one amazing view of the SJNF:
