"Sometimes called the single best boulder in the world, the Mushroom Boulder at Hueco Tanks, Texas, has been closed to climbing to protect the soil, plant life, and possible archaeological resources under the rock. The boulder, located at the base of North Mountain, was closed by Hueco Tanks State Historical Park in mid-December."
Please be sure that the boulder isn't restricted if you plan to climb there in the future. Hopefully, climbers will be able to get some dialog going with the park managers to deal with this issue, reopen the boulder, and mitigate climber impact in the future.
This information is a public crowdsourcing effort between the Access Fund,
and Mountain Project. You should confirm closures, restrictions, and/or related dates.
