Ascent Trip Report

The USGS maps show over 40 possible locations within 39-meter contours (127.9 feet). The highest spot elevation I found is 39.6 meters (129.9 feet) at the old Dorange train station on the Dorchester-Orangeburg county line.

Seeking to simplify Dorchester, I contacted Dave Garber, the GIS coordinator for the county. He seems to understand high-pointing and sent me a map showing the two highest locations from the LiDAR survey. Both spots are at the same address on Mount Pisgah Road.

From US78 at the Dorchester-Orangeburg line, take Durhams Corner Road south for 0.2 miles, turn right on Connelly Farm Road for 0.7 miles, and turn right on Mount Pisgah Road for 0.1 mile. See the nice brick house on the left? LiDAR says the COHP is in the yard north of the house at N33.21578, W80.72473, elevation 131.10 feet, or 39.95 meters. (In deg-min-sec, that's N33:12:56.81, W80:43:29.04). The secondary point is to the left of the gate at their driveway and measures 130.3. This compares closely with the USGS map, which shows a spot elevation of 39.3 meters (129 feet) at the junction of Mount Pisgah and Connelly Farm roads.

No one was home at the house, and from the appearance of the driveway I am guessing this is only a seasonal residence. The gate was locked but not posted, and it's easy to step around.

If you feel compelled to visit all 42 contours in Dorchester County, you have my respect. I don't always trust LiDAR nor take the word of every county GIS guy, but in this case I feel confident claiming Dorchester based on the measured opinion of the local authority.
