Exploring Karst Topography Field Trip

Exploring Karst Topography Field Trip

Saturday, June 1, 2024 (12:00 noon – 4:00 pm)
Led by Bill Jones
Cost: $10

Meet up with Bill Jones at Windy Cove Church at 12:00 noon where we will caravan together in three cars to explore the local karst topography. The complete trip will encompass 47 miles and will take a total of four hours. Be sure to bring good walking shoes, water and snacks. (Limited to 12 people.)

We will begin by driving north on Dry Run Road (609). This road is narrow and has a few drop-offs above the creek when heading north (you are on this stretch for 10 miles). We then end up in Burnsville, and the bulk of the tour is in the Burnsville/Williamsville area. (Note: There is an outhouse at the Postmasters House, but there are no gas stations or stores along the route we will be taking.)

(Note: You will be asked to sign a liability waiver for the visit to the water sinks.)

Trip Details:

  1. We will start with a look at karst features and sinkholes at the Postmasters House (this is now part of the “Virginia Karst Trail”).
  2. We will drive along the dry streambed of Sinking Creek (609).
  3. We will drive into the pancake field and look at the Owl Cave entrance.
  4. We will drive up Limestone Lane and look at the “Water Sinks” blind valley.
  5. We will drive up to “Flood” and then south through the Bullpasture River Gorge (678).
  6. We will walk up to the large “Lockridge/Aqua Spring.”
  7. We will go to Williamsville and the junction of the Cowpasture and Bullpasture Rivers.
  8. We will return to Burnsville by Tower Hill Road.
