Soil and terrain at Back 40
Back 40 is a mountain bike trail network in Bentonville & NWA, AR. The soil is very rocky loam and drains very fast. Heavy tree cover can slow drying after rain. The terrain averages a 1.3° slope at 1,204 ft and mainly faces W. Its nearly flat slopes can hold water in flat stretches. Trails here include Pinyon Creek and Bomb Diggity.
How these factors affect drying
SoilVery rocky loam
About 65% of this ground is rock fragments, so water runs through it faster than the soil type alone suggests. It dries quicker than plain loam. The soil type here is classified, but the exact drying speed is modeled from that classification rather than measured directly at this spot.
CanopyDense 78%
Heavy tree cover shades the soil and blocks wind, so these trails dry slowly and can hold morning damp even after dry days.
TerrainHolds water
Water tends to pool and linger here rather than running off, so the surface can stay damp well after the weather clears.
