The Big Rock

This is not the Big Rock.

When we all lived on Russet Lane in Halesite there was a giant rock across the street behind the Harrison's house.

This is not the Big Rock

I remember it being so large that it was an accomplishment to climb up it.

Small fry like Moe and Jane (on the right) couldn't possibly get up to the top.

Neighbors Chris and John, the boys in the picture, were also too small to get on top or stay there. (We may have shoved them off.)

This is not the Big Rock.

Ten years ago Jane and Bill and I went back to look at the Big Rock.
No surprise----it wasn't that big.

Maybe about this big.

My boyfriend the geologist says it's a glacial erratic.

A definition of a glacial erratic:
After a glacier melts, rock debris is left behind. In the New York region, the Wisconsin Ice Sheet deposited tons of gravel, pebbles and sand—moving, for example, boulders from the Palisades to Central Park—plowed up topsoil, and leveled the earth, filling in depressed areas with glacial till. Individual stray rocks called “glacial erratics” were rounded by the glacier and left behind after the ice melted away. Today these rocks are found across New York City and Long Island.

I'm not going to ask him why it's called the Wisconsin Ice Sheet. We don't need to know.
