Kristi Bumpas, along with Todd and Colin Simpson with DSO, had some (FRIGID) family fun at Oklahoma State University in Stillwater this past week. The field investigation for the new DASNR Teaching Research Lab included pressuremeter (PMT) testing. While PMT testing is always entertaining, it is even more so when the temps drop below freezing! Luckily a propane heater kept things moving along. Thanks, Todd!
