Field Journal #8 — Carson Falls

Location: 972 ft | 37.970, -122.645

The trail began from the road and went up through some forested areas and climbed further up through some plains and serpentine rich areas. The hike looped back around through some a different steep path with turn backs. Many species were not new but the abundance of all the species reminded us of how many  we recognized. We left around 1:20 PM and returned around 5:05 PM. The weather was warm and partly cloudy but overall on neither extreme.
