Rock Run Work Day Report
After two cancellations due to wet conditions, we were finally able to get the limestone sand into position in the headwaters of Rock Run. The high calcium limestone sand (26 tons, $1,500 – your raffle fundraiser dollars at work) was delivered back on May 6 but we had to wait for conditions up on Laurel Mountain to be right in order to move the sand to the banks of the east fork of Rock Run.
The sand will gradually be swept downstream with rain and runoff becoming a part of the stream bed – acting as a buffer for acid precipitation.
We owe Linn Run Park Manager Doug Finger and his staff a big thank you for their help. Doug was able to bring in some heavy equipment making the work even possible. Even with a front loader and dump bed pick-up, it was a lot of work with Doug making numerous trips with the truck himself.
Ralph Koscianski, Denny Hess and Larry Myers of FTTU were there to help out. With this load, we will be set for at least a couple of years.

Rock Run Workday Rescheduled

The workday for Rock Run that had been cancelled twice due to wet conditions has been rescheduled for Monday, August 5, 2019, weather permitting. The goal is to move the limestone sand that was delivered in May to position along the stream banks in the headwaters.
If you want to help out or just want to observe and learn more about the project, we are meeting at 9 a.m. at the Linn Run State Park office which is located on Linn Run Road.
Rock Run Work Day Cancelled
Until further notice, the work day scheduled for Monday, July 22, 2019 at Rock Run has been cancelled due to wet conditions.
We were planning on moving the recent shipment of limestone sand into position along the stream in the headwaters, but the ground is too wet for the equipment to get to where the sand is located.
At this time there is no new date. Once conditions improve, we will reschedule.
Rock Run Work Day Cancelled
