Why Big Sky Resort dries this way

Big Sky Resort sits in the Bozeman & Southwest Montana, MT area, on rocky loam soil that drains fast over terrain that drains at an even, moderate pace. 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 terrain here is rolling (a 6.5° average grade at 7,884 ft) and drains steadily rather than pooling, while the E-facing aspect catches morning sun, so the surface firms up earlier in the day.
