DICKER 1958 (Sept. 10 cont.) we pass into another valley (Banner Canyon). The valley has entirely different vegetation from San Jofie & Eastgate valleys & mammari is basally not present. Vegetation includes juniper, manginita, sand orch, grass, etc. Beyond Banner the road climbs continuously & steeply to Julian which is in the pine country. After getting a few supplies in Julian we headed S toward Mt. Laguna. The road all the way to Mt. Laguna is in high coniferous forest. When we passed the head of Cottonwood Canyon we stopped & looked down into Mescan Valley. The canyon is very steep toward its head & definitely not a passage for D. mammari. It got dark shortly past Cottonwood Mt. Laguna. The road descends slightly into Crack Valley (Crack Meadows) which is a grassy meadow surrounded by forest & not mammari habitat. We continued to get with US 80 & than SE about 1 mi. to Blanchiff Campground. Nowhere along this stretch was there any mammari habitat. We set up camp in the campground & set about 40 traps in a small canyon & along a brush covered slope. Sept 11 Picked my traps. Catech: Peromyscus boylii - 6 Prognathus (Chrotolipus) sp. - 1
