One field trip was a backpacking trip in the Curly Lake Area of the Tobacco Roots. Steve Koehler put up signs pointing the way. Some people will go anywhere for metamorphic rocks. Snow still lay deep on parts of the trail.
Even though it was early July, the glacier lilies were still blooming. This was so long ago, it was before global warming. Curly Lake Camp. On the trail.
Trip leader Tom Hanley (it was his PhD dissertation area) points out cool stuff to Steve Koehler. Some Things Never Change Department:
