The name is from Miwok and means "west hill". It is the tallest mountain in Marin and has many open spaces. It has 100+ miles of trails and fire roads, and is the birthplace of mountain biking. It is a great place to photograph mountains, hills, forests, water features, and wildflowers.
Afternoon fog is rare and "Indian Summer" arrives. It can be warm and sunny. The hills are yellow until rains start.
The western slopes can get large amounts of rain, since the mountain affects weather. The hills are green, creeks are full, and the waterfalls are at their peak, including temporary waterfalls.
The hills go from green to yellow, the creeks are flowing, and wildflowers are abundant.
The afternoon fog rolls in on a regular basis, and the hills are a golden brown.
