314 Compound — Layout & Terrain

Tracks

Track Profile

Our 314 Compound is located next to the North Raccoon River near Scranton, Iowa. At this facility we have 3 full size tracks: one supercross style, one outdoor track with amazing dirt for ruts, and another outdoor track with a much sandier top soil that is whooped out and rough. We also have a long and really fun pit bike track, and the river is great for fishing!

Terrain

Clay-based rut dirt on the main outdoor; sandier top soil that runs whooped out and rough on the third track.

Track DNA — what the dirt is really like

Intermediate

Hard-packLoamSand

▸Loam — the good stuff. Takes ruts, holds a line, and rewards smooth riding. This is the surface most tires and stock suspension are happiest on.
▸Drains well — typically prime 1–2 days after a soak, when it’s tacky instead of slick.
▸High silt (37%) — this dirt turns to DUST when dry. Expect water trucks, hazy late motos, and pack extra air-filter prep.
▸Genuine elevation (~33 m of relief) — real uphills and downhill braking zones, not just man-made jumps. Brakes and fitness matter here.
▸Wettest months: May, Jun, Jul — highest mud/cancellation risk. Prime window: Jul, Aug, Sep.

What do these terms mean? ▾

Sand / Silt / Clay %:: What the topsoil is made of. More sand = looser and faster-draining. More clay = harder, slicker when wet. Silt is the fine dust-maker in between.
Loam:: A balanced sand/silt/clay mix — the tacky, rut-forming dirt riders love.
Blue-groove:: When dry hard-pack gets polished by tires into a shiny dark racing line — grippy for some tires, ice for others.
Drainage class:: USDA’s rating of how fast this ground sheds water — it predicts how soon after rain the track is rideable.
Soil series:: The official USDA name for this exact soil type (like a breed name for dirt).
Relief:: How much the ground rises and falls within the track’s ~1 km square — flat, rolling, or genuinely hilly.
