W. Riemar 1949 Journal 10 July Vicinity Yuma, Yuma Co., Arizona During morning looked for and took several Uma motota in sand dunes W & Winterhaven in Imperial Co., on Calif. side of river. Most were extremely way running long distances to shelter & brush or tree before stopping. Tracks & Chionactis (?) [illegible] not uncommon. Followed one of two sidewinder tracks seen. Took rambling route to, and disappeared into a hole in ground. Afternoon spent writing notes and bathing in canal in town. 11 July Spent all of daylight hours shopping, getting truck fixed, and completing various chores. In evening rode out Calif. side of River on road to Laguna and Imperial Dam. Picked up Lampropeltis getulus yummensis just before dark. Just after dark got small series Rana pipiens beyond Imperial Dam. Just below Dam got 1 Colony on road. Saw nothing rest of evening though temperature and other conditions seemed ideal. Moon did not arise until late. Just before sunset had Bob take picture of me in my new moustache and haircut.
