KESWICK, England — The Lake District National Park Authority has launched a digital permit system for "Sediment-9," a single, waist-high gray boulder located along the Borrowdale Valley footpath, in an effort to combat what officials call "unregulated geological engagement."

Under the new guidelines, which took effect Thursday, hikers wishing to sit on, lean against, or touch the glacial erratic must reserve a 15-minute slot through the park’s mobile app. The rock, which does not feature on any official historic registers, has experienced what park managers describe as "unsustainable physical depreciation" due to its convenient height for resting backpacks.

"We are not trying to gatekeep the outdoors," said Arthur Pendelton, Director of Spatial Flow for the park. "However, the sheer volume of unstructured leaning has led to a critical compaction of the soil surrounding Sediment-9, not to mention severe lichen friction. By introducing a structured queue, we ensure that every visitor has an equitable, pre-authorized encounter with the stone."

Under the "RockPass" pilot program, slots are available daily from 8:00 a.m. to 6:00 p.m. for a booking fee of £4.50. A QR code has been affixed to a low wooden post nearby, allowing park rangers to scan visitors' digital passes. Those found pausing near the boulder without a valid reservation face a £60 fine for "unauthorized lingering in an active geozone."

Some park users have welcomed the predictability. "Normally, you walk up to a rock and you don’t know if someone else is about to sit there," said Clara Vance, a local hiker who successfully booked a 2:15 p.m. slot. "Now, I know exactly when my interaction begins and ends. It removes the social anxiety of sharing a geographic feature."

Park officials confirmed that if the pilot is successful, they plan to expand the system to three additional logs in the autumn.
