SECTIONS IN ACTION Ouray Field Trip
The Colorado Section field trip to the Ouray area was a great success particu- larly because so many folks from western slope and New Mexico, and Dave Palmer from Arizona, participated. An icebreak- er on Friday evening at the Ouray Community Center featured excellent talks by Rick Trujillo on the geologic evolution of the San Juan Mountains and by Bob Larson on the economic geol- ogy of the Silverton Caldera and Ouray area. Bob and Pam Larson were excel- lent hosts and provided great food and beer for this event. Bob was the main trip organizer.
The field trip on Saturday, June
27th, began on the terminal moraine of the Uncompahgre Glacier just north of Ridgeway.
The trip continued to the type sec- tion of the Cutler Formation and the Box Canyon at Ouray. The stop at the Bear Creek Falls overlook provided a excellent view of large amplitude ripple marks in the Uncompahgre Formation quartzite and adjacent phyllites.
The trip continued south to Ironton Park where the eruptive character of the ash flow tuffs from the San Juan calderas was contrasted with the underlying vol- canoclastics of the San Juan Formation. The trip ended at the National Bell Mine, a silicified breccia pipe near the summit of Red Mountain Pass.
A total of 23 speakers, plus the key- note speaker (Dan Rogers) and the panelists (Dan Rogers, Bob Wagner, Grant Trigger, and Jim Cuthbertson) participated in the conference.

Michigan Section Workshop Recap

This year’s workshop was very well attended (it broke last year’s attendance record), with 209 registered partici- pants, and an average daily registration of 205. The technical presentations were filled almost to capacity, with only a few seats left.

The social networking event on Tuesday night was a huge success after the field demonstrations and went well into the night. Participants enjoyed spir- ited discussions, a variety of tasty cold beverages, and snacks. Those individu- als staying at one of the nearby off-site hotels could take advantage of a shuttle service between the hotel and the RAM center.
