On a bitterly cold, rare subzero morning in Norman, the Heisman Park statue of great OU running back Billy Sims stands surrounded by snow containing sastrugi. Obstacle effects related to bow and wake flow rendered areas immediately around the statue’s rectangular base clear of snow, but for the deposition zone on its south side (in a north wind). Fortunately, native Texan Billy didn’t have to contend with conditions like this very often in his playing career!
