Quast 1948 Journal 14 April 13 El Mayor, 30 ft, Rio Hardy, Baja California We are camped about 1/2 mile above a well with a pump and about 1/4 mile north of a point where the Rio Hardy meets the highway. We are 75 yards east of the highway and camped in river bottom material The river Hardy is an old river, judging from the way it meanders in the flood plain. Stretches of the flood plain east of us are green and appear very fertile. Tules grow along the banks and fish may be seen jumping or stirring its surface. A Mexican told us that the fish in the river were Mullet and Catfish. Insects abound here, judging from the numbers gathered around our gasoline lanterns. Included are mosquitoes and gnats in hordes. Three distinct sizes of bats was seen flying overhead just before dark, the smallest one probably being a Pipistrellus. The mountains on the west of us are tilted shale and volcanic rock with large veins of white quartz. Very little is growing on them except an Encelia-like plant widely spaced. The washes are full of creosote and ironwood and are broken by the lingua of alluvial fans that rise high above the wash area.
