The focus of ToMarket’s  Geotourism Journeys is centered on bringing the wisdom and insights of great adventurers to modern geotourists in a fun and entertaining way that also provides a means of economically and environmentally enriching rural communities and ecosystems with a sustainable approach to cultural heritage preservation. The method of this evangelism rests on the recreation of world famous journals in the actual geographical context of their world explorations.

After acquiring an incredibly beautiful 163 acre ranch in Mariposa County, CA, Ken and Teri gained an urgent sense of the current endangered status of rural communities and the environmental stewardship they provide for much of the world’s most beautiful and productive ecosystems. Owning, maintaining and loving the rich habitats found at Birders Homestead Ranch, gave them a deep appreciation of the direct land and water management responsibilities our rural neighbors provide. This experience led to their initiating the John Muir Highway Geotourism Project and evangelizing GEOTOURISM as the best means for protecting these treasures in America and around the world. GEOTOURISM can effectively empower local, rural communities to protect and share their cultural and environmental uniqueness in an approach that retains a rural lifestyle while entertaining geotourists.

Ken began organizing the John Muir Highway Geotourism project effort to name California State Route 132 in honor of John Muir in 2008, crisscrossing Mariposa and Tuolumne counties and other tourism focused conferences and roundtables around California to gain support for the project.  For the history of how this process was completed, readers can go to the following History link and follow the steps needed to get a geotourism project of this kind developed from ground zero to it’s current status hosting the 4th Annual “All Things Muir” festival.

Teri and Ken were pleased to be able to have the Graf-Pulvino Family Fund provide the original grant money to launch the John Muir Geotourism Center (JMGC) in Coulterville, CA, to honor John Muir’s historic ramble route in 1868 from Oakland to Yosemtie Valley. They believe that JMGC’s mission and the dynamic team of board members, staff and volunteers who are developing this effort into a first class geotourism venue and youth education program can bring John Muir’s wisdom to life for visitors on their way to Yosemite National Park. The JMGC team certainly deserves your attention and financial support.
