Powell’s Surveyors at Pipe Spring
Many high places you see jutting out along the Vermilion Cliffs had to be climbed by this team of federal surveyors in winter 1872–73. Explorer John Wesley Powell often camped and resupplied at Pipe Spring. From here the survey team set up triangulation stations on ridges and summits with clear lines of sight. The detailed canyon country maps that Powell’s men made established a key base line for the territorial survey. Their triangulations revealed Pipe Spring to be in Arizona Territory, not in Utah Territory, as previously thought.
