Quast 1948 Journal 152 July 13 Catalina, 850+ ft., Baja California hot trip from previous camp. Minimum temperature last night was 55° F. Catalina is a small ranch located above a sandy wash. The ranch is surrounded on all sides by granite boulders of all sizes and the soil is gravelly, being of decomposed granite. Four or five large mesquite grow around the houses and about fifteen palm trees some of which are very tall grow in the wash and in a small gulley south of the houses. The earlier ranch is located about 300 yds down the wash (west) and it is owned by the father of the proprietor here. Water occurs here in a small pond formed by a dam in the gulley 200 feet south of the house. This water is used for irrigating a few squash plants and fig trees near the main wash. Water is at the present time running down the gulley to the wash where it forms several small ponds before it disappears. Another pond west of the house and near the fig trees is also used for irrigation. Shot bats last night in the wash west of the houses and obtained 4 Pipistrellus hesperus. This species appeared before sundown, a pair being seen flying together down the wash. Murray obtained one Eptesicus fuscus also & Dr. Benson a Dasypeltis egg.
