Why Mahlon Dickerson Reservation dries this way

Terrain & soil

Mahlon Dickerson Reservation (North Jersey, NJ) rides on loam soil that drains well over terrain that holds water and dries slowly. Heavy tree cover holds the damp in, so it stays wet longer than the sky overhead would suggest. Loam reads that exact ground against live weather, rather than leaning on a regional forecast that can’t tell you what the dirt is doing. The terrain here is gentle (a 2.1° average grade at 1,322 ft) and drains slowly enough that low spots stay soft after a storm, while the SSW-facing aspect soaks up sun through the middle of the day, which speeds drying and opens the season earlier.
