No site in New York's access file falls on Dry Brook, so the way in is public ground and road crossings rather than a marked landing. 3 blocks of public land front Dry Brook, and 1.7 of its 3.8 mapped miles run through them.
Slide Mountain Wilderness — state conservation department, 1.29 mi of this river, 50,751 acres in all, restricted access
New York City Lands — city land, 0.3 mi of this river, 968 acres in all
Bushkill — city land, 0.12 mi of this river, 441 acres in all, access unrecorded
Ownership from PAD-US as the state publishes it. Where a block has its own page, the name
links to it. The river miles are how far this river's drawn axis runs inside each block, measured here;
the acreage is the whole unit's, most of which is nowhere near this water. "Restricted access" and "access unrecorded" are PAD-US's own words for the block, and
neither one means open — check before you park.
