“Leave No Trace” is not a new concept for most outdoor enthusiasts but the LNT recommendations for engaging with the outdoors are always updating as new learnings evolve. We talk with Ben Lawhon, the head of LNT’s research team about the science behind the curriculum of LNT. For this episode, we’ve partnered with the Leave No Trace Center for Outdoor Ethics in advance of the upcoming Arches Leave No Trace Hotspot Sep 24-27th. An event that is working to help address the mountain recreation problems in Arches National Park.
