The wilderness and geology explorer John Muir was born on April 21st 1838, and would become an influential naturalist and conservationist advocate. Gavin and Wyatt look to Muir for a bowl of kibble, bones, and biscuit treats for dinner while John looks to the library for a list of mountain, ice, and wild music for the show. Hikers, walkers, and ramblers of all sorts are invited to join the John Muir birthday celebration on Crosscurrents, 4/21 at 8 a.m.
