We hiked for a couple of miles on Hunter Island in Pelham Bay Park, Bronx, New York. It’s a nice place to take a walk. These were shot with our Samsung Galaxy phones.

We took a walk in Pelham Bay Park in the Bronx, New York on February 16, 2022. I replaced the skies in most of these.

I love the folded and layered metamorphic Fordham Gneiss, which is part of the Hartland Formation that forms the bedrock beneath the Bronx east of Cameron’s Line. The rock consists of granitic and garnetiferous amphibolite gneiss with numerous light-colored quartz veins and migmatite dikes. Migmatite is a type of igneous rock that forms when metamorphic processes begin to melt the rock under high temperature. Felsic minerals melt and are injected into joints, faults, and other zones of weakness in the rock. As it gradually cools, bands of feldspar and quartz crystals form along the edges of the intrusion. The center of the migmatite veins typically consist of larger crystals of feldspar and quartz. In some cases, the dikes cut across older dikes and quartz-filled veins; many are folded, or display offset by faulting. Overlying the bedrock is a blanket of glacial till. The beach is littered with large erratics derived from bedrock sources nearby. (Source: NYC Regional Geology (geologycafe.com))

After walking to the end of Hunter Island we drove to City Island for a meal at the Lobster House.

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).

Afternoon at Pelham

Last Friday we went to Pelham Bay Park, Bronx, New York in the afternoon and had a 3 mile hike around Hunter Island. The views are lovely, but it was hot and buggy. After that we drove to the Lobster Shack on City Island to buy a take out. While parked off the road in a driveway a crew cab pickup truck scraped the paint off the edge of our side mirror. The list of mishaps grows long for our little VW Jetta “James”. We’ve only had it a couple of months.
