Trail Work - 7/11/26

Worked in Guyton, using "lift and tilt", to create a raised trail bed of compacted dirt, to rectify what had been two rooty, washed out, widening switch backs. Goal was to re-establish the line, compact the tread, and angle it such that water sheets off the trail. Strategic rock placements and attention to drainage should ensure a lasting elevated line. Also did much needed trimming on "Poplar I Mean Sycamore". Great turnout today!​

Trail Work - 6/14/26

We installed mud sills/bridge supports for the Waterfall Trail bridge. This was to help level it out and stabilize it, while we await approval for a full bridge replacement, which will utilize the new mud sills. We also cleared drains along the Flats from Harford Road and did some extensive trimming, that was sorely needed. Big thanks to our modest but mighty crew today!

Trail Work - 5/16/26

Worked in the southern most part of Little Gunpowder, Franklinville. The white trail that enters off Vinegar Hill Rd, just before the green steel bridge, has been deteriorating and becoming unsustainable. The trail was moved uphill and connected to an alternate exit slightly further up the road. This will provide a more sustainable access to this section of trail.​

Trail Work - 4/18/26

Replaced an old small bridge with a more robust puncheon on the A-Side Flats, between Harford and Bel Air Roads. Also performed significant cut back of encroaching growth on both the A-Side Flats and the Old Blue trail. We appreciate everyone who made it out!

Work was done on The Hasselhoff trail near the small bridge, restoring the trail tread, de-berming, adding drainage, and regrading of the trail surface that had significantly deteriorated over the winter. Significant cut back was done on the Lazy Man and Shelter Rock trails and a root ball hole from a fallen tree was filled on the Cliffs of Insanity trail. A big thank you to all that came out!

A Look Back at 2025

From night rides to snow rides, from our first LGP race (6 Hours at the Mill) to the MORE Get To Know LGP Ride, from multiple puncheon builds to the Amy's Bridge replacement, from trail work to clearing trees, from riding with kids to riding in pajamas, it was a full and fulfilling year in 2025!

Trail Work - 2024

The year began with extensive storm clean up and restoring stream crossings. Then restored the raised trail bed on the A-side flats and used pavers for a reroute of a collapsing section. Made a visit to the Big Gunpowder for tree clearing, trimming and armoring. Some reroutes were done on the Flats. Focused on Franklinville, reworking a section of deteriorating trail and rerouting the low-lying trail up onto the ridge. Worked on Winterfell and the Split Log Climb. Finished up with various repairs in Guyton. Much was accomplished!

Another busy year! We created a raised trail bed on low-lying sections of the Flats, to make the trail more weather-resistant and usable throughout the year, gave some love to the Big Gunpowder trails, maintenance of the Flats and significant trimming as always, rerouted a portion of the Guyton Flats, where we were losing trail, created additional parking at the Laurel Brook / Bottom road parking area​ and built up and reinforced the section of trail near the Triple Creek crossing.

Trail Work - 2018

Seven trail work events this year resulted in a shifted waterfall trail, with some rock armoring in the middle, water diversion in the meadow, a reroute of the white trail, just off of Bottom Rd, a significant effort to create a more beginner-friendly line on the flats between Harford and Bel Air Rds and a raised turnpike as well, repaired the eroded side trail by the steps off of the Bel Air Rd parking lot and rerouted the trail that descends from the rail bed below Petticoat Junction.
​

Trail Work - 2017

A very active year started with  relocating a  structure to cover and protect a bee hive oven at Jerusalem Mill. Then there was the switchback to the railbed, a waterfall trail reroute, a bridge build to replace the Pleasantville plank, clearing of Railroad Pass 3, some raised trail beds, a new hiker crossing at the top of the waterfall and lastly, the trail that parallels Bottom Rd. There were some big rides, with 50+ people for the MORE Discovery Ride and 30+ for the 3rd Annual Memorial Ride for Jesse.

Trail Work - 2015

Plenty of work was done, but before we really started documenting it! The chicken wire bridge was rebuilt, twice, on The B-Side flats and a muddy stretch of the Flats was rerouted into the meadow, to name a couple.

High Water in the Park - June 2015

Water ravaged through the park after heavy rains. Reroute created away from the bank that is eroding away.  Trail tread with ankle deep water showed where we needed to cut some drains.

Trail Work - 2014

Improvements were made at several locations along the white-blazed Little Gunpowder Trail, before we kept track and really posted such work.
