Why Mt. Tom State Reservation dries this way

Terrain & soil

Mt. Tom State Reservation sits in the Pioneer Valley, MA area, on loam soil that drains well over terrain that drains at an even, moderate pace. Heavy tree cover holds the damp in, so it stays wet longer than the sky overhead would suggest. Whether it’s worth riding comes down to how that ground sheds and holds water after rain. That’s exactly what Loam tracks, hour by hour. The SSE-facing aspect soaks up sun through the middle of the day, which speeds drying and opens the season earlier, and the rolling terrain, about a 6.6° average grade at 272 ft, drains steadily rather than pooling.
