Why Back 40 dries this way
Terrain & soilBack 40 is a mountain bike network in the Bentonville & NWA region of AR, riding on very rocky loam soil that drains very fast 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. What really sets the timing here is how quickly that ground gives back a firm, dry surface, not what the day’s forecast says. The W-facing aspect gets its strongest sun in the afternoon, so morning laps can stay tacky after overnight moisture, and the nearly flat terrain, about a 1.3° average grade at 1,204 ft, lets water sit, so the flat stretches are the last to firm up. Named trails in this network 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.
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.

FAQ
Common questionsCan you ride Back 40 right now?
As of the latest update, Back 40 is Rideable now (PRIME). No significant rain in the forecast. No measurable rain in the past week.
What is the soil and trail surface like at Back 40?
Back 40 sits on very rocky loam soil that drains very fast. 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.
How long does Back 40 take to dry after rain?
Back 40 drains fast: about 65% of the ground is rock, so it sheds water and firms up much sooner than the soil type alone would suggest. Its terrain holds water in low spots, which slows it. Heavy tree cover slows drying further.
Does Back 40 get snow in winter?
Rarely. Back 40 sits low and mild enough (around 1,204 ft) that snow seldom affects riding; conditions are driven by rain and drying. Loam still flags FROZEN on the rare freeze.
What trails are at Back 40?
Named trails at Back 40 include Rago, Blowing Springs-Connector, Back 40, Pinyon Creek and Bomb Diggity. That is a sample of what our map data covers rather than a full inventory, and local trail counts change as networks are built out. Loam models conditions for Back 40 as a whole, so the verdict on this page covers the network rather than scoring each trail separately.
What's the terrain and elevation like at Back 40?
Back 40 sits at roughly 1,204 feet, faces mostly W, and averages a 1.3° grade with about 78% tree cover. That makes it an afternoon-sun network where mornings run tackier, and the nearly flat grade means it holds puddles in the flats. Loam models this exact ground against live weather rather than using one regional forecast.
When is the best time of year to ride Back 40?
There is no real off-season at Back 40: snow rarely interferes, so good days come down to rain and how fast the dirt dries. The live verdict above reflects today.
