Berthoud, Oct 18, 1907
Started at 8:30 driving west and north. Hazy over the mountains and a cold northerly breeze blowing, changing later to easterly. North of Lone Tree Lake I found a strong outcrop of typical Hygiene sandstone dipping SE, 15˚, continuing NE to SW corner of Loveland. Its strike continued SE would about meet the outcrop west of Berthoud. No fossils.
