  • The Smoody Family for reconnoitering the area for years.

  • The park rangers for warmly welcoming us and giving us a wonderful tour of the Cloud Cap Inn.
  • Eric & Paul for organizing a last minute car load of participants.
  • Most of all to Bo! — for devoting so much time and energy in researching the geology and preparing such a concise, to the point, field trip guide.

President Janet's SE Oregon Scouting Trip (Take Two)

On Monday, June 1, Jan Kessler and I headed down to SE Oregon to scout my field trip stops for the September GSOC trip. My husband Doug and I did a preliminary trip last August.

We had Marli Miller's new Roadside Geology of Oregon with us so the navigator could read aloud from it as we travelled. It was very helpful. We stopped at Glass Buttes off Hwy 20 between Bend and Burns. Neither of us had been there before. The turnoff is on the south side of the highway, just west of milepost 77. Look for a cattle guard. I was disappointed that it wasn't a sparkling glass mountain as I had imagined.
