Speedbowl Valley Raceway

1/4 mile clay oval track created in 1946. Modifieds, sprint cars, and stock cars race here. This track has previously been known as Amarillo Speed Bowl, Amarillo Speedway, Dirt Track Speedway, and Randy's Speedbowl.

December 2014 update - the track's official web site was offline, and I cannot find any evidence that the track is still operating.
