7/31/87 Drove to Thermopolis, Wyo. from Marmarth, N.D. (410 mi). went by way of Elkaka, Mont. and spoke w/ Marshall Lambert at The Carter Co. Museum. & Showed us a baby Pachycephalo- saurus skull he had found near Elkaka. Talked of his work with the museum and how he has had very little help in keeping it up or building it. The museum is in a new location since my visit to the basement of the high school in the late 60's. Marshall has added to an old garage that forms the nucleus of the museum. From there we took the gravel and dirt road to Powellville across some wide open prairie and broken, pine-forest rims and buttes. crossed Beaver Divide & went past "Claw Butte!" Last traces of the Eastern deciduous forest passed shortly after dropping off the Beaver Flats rim before the divide between Beaver creek and the Powder River Green Ash, American or Red Elm in gallery x woodlands.
