A Lava Tube! Also, RARE Orientation
This here is the entrance to a lava tube out in the Cascades. These long tubes - caves, essentially - formed as flowing lava cooled on its surface and continued to flow underneath the cooled shell:
Lava usually leaves the point of eruption in channels. These channels tend to stay very hot as their surroundings cool. This means they slowly develop walls around them as the surrounding lava cools and/or as the channel melts its way deeper. These channels can get deep enough to crust over, forming an insulating tube that keeps the lava molten and serves as a conduit for the flowing lava. These types of lava tubes tend to be closer to the lava eruption point. (Wikipedia)
Click on the pic to see my set of photos from the cave, the Cascades, and RARE Orientation.
UPDATE: just added some photo descriptions for those pics. I'd forgotten to do that.

Your photos are great, Sarah! I can't wait to see what you can do with an SLR.
Not that you need one, of course....because these are impressive enough, but...you know what I mean. I'm jealous!!

Thanks Marc! If I put in the time to do any post-processing or editing, they'd be better.. but I never get around to it. Speaking of photos, what have you been shooting lately?

Besides the RARE stuff, some shots of my buddy's adorable family, a drive around Lane, Linn, and Benton counties for work, and a farmer's market I went to today. I'm planning on getting the 'pro' account and loading up a bunch of stuff soon. Trying to finish that project we have due Friday....not very excited about it as my time is already short with work (evening public meetings this week), finding a place to live (yeah, I'm being very picky since I may be staying here for awhile!), and studying for an exam I'm sure I'm going to fail next month. Taking off to California next weekend for a wedding party. Really looking forward to that and coming back to spend the following week with the RARE group!
