I went to San Lorenzo Canyon last night for a Geology Club barbecue. I finally bought a digital camera and I took it with me. Unfortunalty I don't have the memory card for it yet. There is a cool rock fromation on the way to the canyon that I have wanted to get a picture of , and I finnaly got one.
This is the rock formation, it is a very obviouse unconformaty (where the rocks were deposited as flat layers, rotated, eroded, then new layers were depostied on top) If you look at the bottom of the picture you can see where this summers rains cut out the arroyo. The road to the canyon is an arroyo, and the canyon is kinda like a slot canyon.
Here is a zoomed in picture of the rock
This is inside the canyon. There was even a little water still flowing. The water must have been 4 feet deep or more during the hight of the flash floods (from looking at sandbars). In theis picture you can see were the channel has been cut, it is at least three feet deeper then it was last time i was out there. This is a favorate place to hold barbeques and dinners for the Earth Environmental Science Department. This is where they take all the prospective grad students when they come to visit.
The sunset in the canyon, to bad I ran out of space on my massive 16 mb card, it got even better. I can't wait untill my 1 Gb card gets here.

Sounds like you had a good trip. That is definetly a unusual rock formation. How old is it?
Those are some good shots. What camera did you end up getting?
Awesome pictures, dude. I've very jealous. Also, thanks for the reminder on what unconformities are. I still sometimes confuse them with nonconformities. Depositional disconformities I usually remember, thanks to that stretch of the Wasatch range behind Willard.
At any rate, thanks for posting again. I expect more frequent posts now that you have a digital medium capturing device to take with you.
