LPL Canyon de Chelly National Park Trip, Day 1 Part A

At the San Manuel copper mine. From left, Dave Trilling, Dr. Jay Melosh, Joe Spitale, Jim Head, Dave O'brien, Paul Withers.

Here's everyone nicely backlit watching Dave's talk on the mine.

Dave O'brien giving the copper mine talk, complete with barbed wire fencing.

This is the canyon where we all got stopped for 1/2 hour for construction. It was somewhere between the Salt River Canyon and San Manuel, but I don't remember precisely where.

Closeup of the river at the bottom of the canyon

Here's me using my canyon-height-testing method of throwing a rock over the edge and counting how long it takes to hit bottom. Only gives a lower estimate, as I can't throw a rock all the way to the middle of the canyon.

Another shot of same thing, this time with Jay Melosh looking on.

Me and Werner looking over the edge.
