Field journal #10 — Upper Mount Tam

Location: 784 ft above sea level | 37.924, -122.596

This is the first half of a carefully calculated hike which was so graciously planned to take place along the vector of gravity. This has benefited those less inclined to physical activity. The hike began from a parking lot where the side trail lead us off downward along the side of the mountain. The real genius of the hike was in the fact that other drivers were brought to pick us up at the end so that we did not have to work our way back up. We arrive around 1:25 pm and left around 4:25 pm. The weather was sunny with strong breeze and overall pleasant.
