Field Day at Toms Creek

Yesterday, some of our team members were lucky enough to enjoy the lovely fall weather in Pilot Mountain! Pebble counts and sediment samples are always better when the weather is perfect! This site is extra fun to work at because we always get an animal field crew that tags along!

Look what we FOUND!

Our field staff found these projectile points within inches of each other on a gravel bar within a stream. The larger lanceolate spear point is likely a "Guilford flat base" point from the Middle Archaic Period (5200-6000 years ago). The smaller is broken near the top so a tougher ID. It appears to be a type of stemmed or notched projectile from the Early to Middle Archaic Period, so these were potentially made hundreds to thousands of years apart from each other.  Both pieces are made of rhyolite from the Carolina Slate Belt region.

Green Treefrog Hitchhiker!

While in the field today at the Pen Dell Site in Johnston County, NC we found a Green Treefrog. The little guy decided to hitch a ride on our GPS tablet.

Fun Fact: "Herpetologists have found that this species and other treefrogs will occupy plastic PVC pipes that are placed around wetlands. This method has been used to monitor populations of treefrogs in North Carolina." Click here to learn more fun facts about Green Treefrogs!

White irisette

Sisyrinchium dichotomum

This week some of our WLS staff had the opportunity to conduct an endangered species survey for the White irisette. The survey was completed in Polk County, NC. This perennial herb lives on mid-elevation slopes in dry to moderate moisture oak hickory forests. They like partial sunlight and grow from 10 to 16 inches tall. Good news! Many of the previously documented areas of occurrence were located! The White irisette is threatened by human disturbances, with residential development and road development being the biggest disturbances.

A bonus of the trip was getting to observe beautiful views from the top of White Oak Mountain!
