Walk Tuesday, November 02, 2011

The days are short and I started late so the light was weak. So the photographs are weak.

I took my shirt pocket Nikon camera. Poor camera. Nice to carry.
*

This is only my third rock-walk.

I’ve been reading Geology. Now I’m trying to observe what I have been reading about.
*

My understanding is weaker than the light. I am limited to photographing rocks that look different. Explanation for their differences has to wait.
*

My reading says that Beacon Hill is mostly granite on one side and gneiss on the other with a major fault between that has created mylonites.

The granites will have a coherent appearance. The gneiss will look to be layered. I am uncertain about the look of the mylonites. It seems that they may or may not be ‘layered’. They are to have elongated minerals.

I see rocks that have a couple of colors of green and some rocks that look rather blue or blue-green.

I saw one batch of rock that had some of the look of sedimentary rock.

I processed the photo of one scrap of granite with another rock incorporated in it by running up the saturation. In hindsight I think the ‘false colors’, blue and orange, only reflect the lighting, the blue of the sky and the orange of the sunset.
*

I suppose the whitish ‘bands’ in the rocks are quartz. I noticed white bands with a wrinkled look on an exposure in the road. I had to use flash to photograph it.
*

I didn’t go to the top of the hill.

I walked up the hill taking pictures for 30 minutes. The walk down the hill was 15 minutes taking a few pictures. I made 107 exposures. I’ve kept 64, all with some manipulation. Sometimes it was only cropping. The manipulation is noted on my filed copies of the photos.

I suppose I was only walking about 10 minutes up the hill. However, I am delighted that my legs and lungs survived the effort as well as they did. My feet tired badly. Balance was a problem at the end of the walk. I will do something about that in the gym.
*

There are quite a few ‘road-scape’ photos, meant to remind me just where it was that I walked. They might help if I want to find the rocks I photographed again.

There are ‘landscape’ photos I made just for fun.
*

I photographed most of the major outcrops I passed. One interesting outcrop I didn’t photograph was behind a screen of trees.

A lot of the photos are rocks that were exposed in the road.
