Field Journal #9 – Ring Mountain

Location: 486 ft above sea level | 37.913, -122.488

The hike began up on a residential hillside zone and as we walked past the mansions we were all tempted to find a high reward job which may or not be high risk. In reality we just walked up to the entrance of the trail which opened up from a street to a large rolling hills plain with a view to Mt. Tamalpais. The general feel for the area was like this and was not a very intense hike from our starting point. Lots of disturbed and serpentine rich areas were found on our hike and we were able to find many previously observed species and a few new species.
