I first hiked up Flattop Mountain as part of a Hanshew Junior High School cross-country running team practice. We went the standard route. Many subsequent trips have occurred, some from the Canyon Road trailhead and some from the Powerline Trail to the north. A recent trip was on September 30, 2006, with my five-year-old niece for her second ascent of the mountain. I climbed Flattop Mountain again on March 14, 2008, and again on May 10, 2008.
