Field Journal #6 – San Bruno State Park

Location: 682 ft | 37.776,-122.493

Trail began from the parking space atop the hill at the base of a radio tower. We traveled downward through a winding path which looped back to the road leading back up to the parking space. Most of the area was green and full of many species — which made the area seem like the perfect review space. The area was highly diverse but had little in the way of trees which must have prevented shade niche species. We arrived to the trail around 1 PM and left around 3:30 PM to stop by a popular food joint for whatever reason. The day was sunny but more on the colder side due to the altitude and plenty of wind.
