Note the prominent layer of white ash near the hammer.

Hiking to Pulpit Rock, Colorado Springs, CO

Looking for shark teeth in Laramie (reworked sediments). Note the hands & knees posture which is required to search for such small objects.

Bob Raynolds arguing his case for the geology near Pulpit Rock. Eventually, he won the argument with considerable digging by Jim to support his case. Kirk Johnson went downstream to search for evidence supporting his claim but ended up convincing himself of Bob's argument. Thus, the new leaf locality Kirk discovered is now called "Lost Argument". The beauty of science is that you don't live by personal bias. You change your views based on the evidence provided in the rock record - period.

Examining the base of the sandstones present near the top of Pulpit Rock.

A geologic anamoly which has yet to be explained. Here we see river sandstone deposits (with crossbeds) overlying what Bob calls a "Mystery Slurry" material from a significant landslide or mudslide. It's clear that an unconformity exists here, probably due to the ancient river digging down into the bedrock below it.

One of the luxuries of the Kiowa Fair Grounds - inside the metal bldg are a few offices and this meeting room which we used for our evening lectures.
