Soil & Geology — Stephens County
Stephens County red dirt and limestone with sandy lenses — regional rock profiles between Lawton caliche and Ardmore lake soils without either city's dominant signature.
Duncan bores encounter Stephens County red dirt with limestone and sandy lenses — penetration changes on US-81 commercial approaches. Less caliche than Lawton west and less lake groundwater than Ardmore east. South industrial fill can hide shallow rock sting without correct bit selection.
Weather & Scheduling
South-central heat and prairie wind — summer dominates US-81 pulls; spring storms soften Stephens County ROW on Chisholm Trail approaches.
Summer heat dominates crew scheduling on US-81 pulls. Spring storms soften ROW briefly. We plan entry timing around weather, not against prairie wind on long highway shots.
