Wind your way on the AZT: Arizona Trail between Marshall Lake and Fisher Point offers a quiet way to enjoy the return of warmer weather

Arizona Daily Sun (June 26, 2022) by Larry Hendricks I lean back against a log and listen to the ponderosas tell stories to the land. The stellar jays and crows share secrets in a language I want to understand. I count flower petals and pine needles that bounce on the breeze. The dog pants and laps cool water from my hand. I am here, at lease, and my worries burn away like morning fog. Old friends of mine, the sections of the Arizona Trail that approach and pass through Flagstaff carry with them a yearning to, one day, hike the entire 790 miles from one end of the state to the other. My dream, like many hikers, is to trudge the whole trail before I’m too old to get it done. Some hikers decide to hike the entire trail in one go, taking more than a month to do so. Other hikers like to attack the trail piecemeal, bit by bit. Some hikers, like my good friend Bob Reynolds, schedule larger sections. His plan is to cover about 180 miles over the course of 10 days. In between spring storms, I decided recently to start out from the Marshall Lake...

Trail Skills Institute Module 3 – April 2018

This year's TSI Module on Stone Maintenance Structures was held near Flagstaff on the Lakeview Connector Trail on Passage 30, Anderson Mesa. This connector trail was built by the ATA to allow users to access the Lakeview Campground, and to allow campground users better access to the trail, which is just at the top of the mesa beyond a short but rugged cliff band. This short connector is an important access point, and it offers excellent opportunities to study when and how to use stone structures in trail construction and maintenance. ACE instructors Mark Loseth and Matt Roberts taught the basics of stone work to ten participants from all over Arizona. To preserve the steepest portion of the trail that breaks through the basalt cliff, the group studied how to create backed bars, armored drains and sustainable steps from the ample material available onsite. Dry stone masonry is an art form, and Matt and Mark were excellent at providing an introduction to the craft. Over 2 days, the team divided into groups and each tried to perfect their own construction and learn from each of the varied projects. We were even treated to a visit from a through hiker who...
