Pemberton Springs & Crawford Prairie Field Trip Report

Pemberton Springs/Crawford Prairie field trip Report (3/23/19)

Ben Sandifer gives us some history and an orientation to the 15 acre site. We were excited to see Dallas Park Board member Becky Rader (center) there too!

FW-NPAT Chapter members Jeff Quayle, Chris Homkomp and Donna Homkomp at gather up.

Ben also shared information about this historic bur oak tree which is estimated to have sprouted in Revolutionary War times.

John Snowden of Bluestem Nursery (orange hat protector) has donated a lot of plants to the restoration underway there.

A member of the Pemberton family still lives at the top of the hill above the spring. Without their family’s vigilance and stewardship of the area the spring would likely have been lost long ago.

The spring bubbles out of the ground at a geologic contact point between a sandy Pleistocene deposit and Austin chalk. The water is at least 600 years old (carbon dated) and is currently flowing at a rate of around 40 gallons/minute.

Discussion about restoration projects and the site’s use and disturbance history.

Rich Grayson, one of the primary site stewards, providing more information as we first viewed the spring.

There’s a smaller secondary spring located about a meter higher up the slope that Ben considers a bellwether for the flow rate of the Big Spring.
