Yeates Hollow: is greater than 40 inches to quartzite bedrock
GEOGRAPHIC SETTING: Tickville soils.
Parent material: colluvium over residuum derived from andesite.
Landform: volcanic affected mountain slopes.
Slopes: 8 to 60 percent
Elevation: 4,800 to 6,800 feet
Mean annual air temperature: 41 to 45 degrees F.
Mean annual precipitation: 16 to 22 inches.
Wettest months: October to May.
Driest months: June to September.
