Marc and I went to Pelham Bay Park : NYC Parks in March. I like to make landscape photographs of the rocks and water. The colors were blue sky, yellow grass, and gray rocks. I added assorted skies and coloring.
The shoreline in Pelham Bay Park is crystalline basement rock of the Hartland Formation and part of Cameron’s Line. The park also has a variety of glacial materials and features.
The park encompasses 2,764 acres of coastal lowland. The Hunter Island Marine Zoology and Geology Sanctuary is on the north side of the Orchard Beach bathing area, and includes the northeastern shoreline of Hunter Island, and all of Twin Islands, Two Trees Island, and Cat Briar Island.
The Hartland Formation consists of granitic and garnetiferous amphibolite gneiss with many quartz veins and Migmatite dikes. Migmatite is an igneous rock that forms when metamorphic rocks begin to melt under high temperature. Felsic minerals melt and are injected into the surrounding rock along joints and faults in the rock. As the igneous material cools, bands of feldspar and quartz crystals form along the edges of the intrusion. The center of the migmatite veins contain larger crystals of feldspar and quartz. Migmatite stands out in outcrops as light-colored bands in the darker amphibolite gneiss host rock. Some dikes cut across older dikes and quartz-filled veins; many are folded or are offset by faulting. Overlying the bedrock is glacial till and numerous erratics.

I haven’t got a clue about the detailed description, but you pictures are glorious 🙂
My major was geology so I love rocks. To me that description is clear. I simplified it. Glad you like my editing of the pictures. Sky replacements help. We are off to take pictures at the botanical gardens today.
Have fun
All are beautifully captured!
Thanks Amy. The before editing pictures were very dull.
