An epic adventure, page after page!
Format: Paperback
Many women dream of making this hike (I once did) but few lace up their boots and get on the trail. And even a tiny fraction of those who DO realize their goal, could capture the experience like Joan Griffin. I read several chapters a night and always looked forward to getting back on the trail with her from my rocking chair. The grandeur of the sights, the wonder of seeing the world well above 8,000 feet ~ for 27 days ~ reads like a personal diary. Every perspective, high and low, is captured: the practical issues of carrying on even with a twisted ankle on Day 1, then blisters, surviving sudden weather changes, confronting inner doubts, securing essential food and water, and losing the camera enrich the book in an authentic style. In between all this, the reader remembers that it all took place with 40 pound backpacks on their backs! It's a magical but real-life journey with the inevitable personality differences of the Three Women, as well as their uniquely personal reasons to hike. As the brave heroes arrive to the finish line, one is aware of the power of grace that accompanied them all along. Yes, this experience changed the hikers but it also changes the reader. Being aware of those who live curiously and courageously provides a kind of encouragement for us to do the same, even after age 50.

Inspirational Read
Format: Paperback, Format: Paperback
Griffin, J. M. (2023). Force of nature: Three women tackle the John Muir Trail. Black Rose Writing. Joan Griffin loves exploring and lives in the Northern California foothills of the Sierra Nevada. Five legs, 27 days, 195.9 miles, this is a memoir of three 50+ women hiking the John Muir Trail located in the Sierra Nevada Mountain range. Each day receives its own chapter providing a vivid description of the trail, challenges, and beauty. Walking created an "unpredictable reality," that was "bigger in every conceivable way than [her] imagination could have conjured." As you read through the story, you are transported to the trail, so vivid her recollections and descriptions of their experiences. She wore a necklace with the words strength, courage, and spirit; a mantra that served her well along the journey. Griffin found: "I found my very soul had acclimated to the natural world, and I was completely in tune with the Earth and the sky and the water surrounding me." Such an inspiring memoir! This would be a good read for 50+ women who need a good dose of inspiration, those who like travel memoirs, and those interested in long-haul walking.

A great tale of women trekking together
Format: Kindle
This is well -written, enjoyable to read, and like the three women on the trail as a reader you don't want it to end as they near the end of the JMT. Filled with beautiful descriptions of scenery, humorous retelling of some difficult days, and interesting encounters with other people. Even for the non-hiker this book is a fun read.
