Boudinage

Revisiting an old image for reprocessing. Pelham Bay has lots of Fordham gneiss. Here is a dense article on the Bedrock Geology of New York City: More than 600 m.y. of geologic history (sunysb.edu). I love geology. It was my manor at Hunter College.

Geology lesson: Boudinage is a structure which is sometimes present in metamorphic rocks apparently as a result of tension and in which a competent bed is thinned and thickened so that it resembles in cross section a string of sausages (Webster’s).

Local Nature

Over the last several days we went out for short walks to stretch our legs while maintaining “social distance”. Here is a selection of plants. The multi-color schist used in the wall along the Hudson River Park has pink feldspar and green feldspar coloring the layers. I used my Samsung Note 10+ to photograph these.

Sydney Trees and Rocks

13th posting of photographs of Sydney August, 2015

Rocks thrill me and I love trees. I studied geology and worked as an environmental educator so when I travel I always pay attention to the inorganic as well as organic features in the environment. Here are some of the sandstone formations, eucalyptus trees, and fig trees of Sydney, Australia.
