Maintenance is attributed by a small sign to the Custer Prairie Roads Advisory Committee at the south edge of Marlowe Butte, where beside a graded county road and a turnout with a sun-faded rules board the County Dust Palliative Trial Strip preserves five adjacent test lanes treated with different dust-control compounds. A small sign attributes ongoing maintenance to the Custer Prairie Roads Advisory Committee, although the painted lane labels appear to have been refreshed more recently than the committee itself. Reportedly installed so ranchers, road crews, and procurement staff could compare chloride, lignin, and polymer treatments under ordinary traffic, the strip now functions as an unofficial roadside exhibit. One hook detail worth verification is the presence of a locked coin-operated misting cabinet labeled CALIBRATION USE ONLY, which may no longer be connected to anything.
