Pelham in Winter

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.

Staten Island

We spent a short time on Staten Island before taking the Ferry back to New York City.

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).

Rye and Meadowlands

We had a lovely trip birding with the Linnaean Society of NY to Rye Playlands and the Meadowland Conservancy in Westchester County, New York. The highlights were a flock of Snow Buntings, a Cooper’s Hawk, and a White-Fronted Goose.

Cold Spring and Cove Neck

Cold Spring Harbor, Nassau County, Long Island, NY About The Village | Cold Spring, NY was the start of a lovely day. We ate lunch at a lovely restaurant, the Harbor Mist, by Oyster Bay inlet on the Long Island Sound. There is a little park there dedicated to Billy Joel. Cold Spring Harbor was the name of Billy Joel’s first album in November 1, 1971.

Next we drove to Cove Neck on the opposite shore to see Sagamore Hill. Sagamore Hill was the home of Theodore Roosevelt, 26th President of the United States, from 1885 until his death in 1919. There is lots of history and pictures at the Sagamore Hill National Historic Site, NPS site. I installed The NPS App – Digital (U.S. National Park Service) app and watched VR tours of Sagamore Hill National Historic Site.

Soldier in a Tree

We went to Green-Wood Cemetery, Brooklyn, NY on Thursday and I thought I saw a ghost of a civil war soldier in this tree stump.
