Still aglow from the 25th anniversary reunion of my Isotope Cosmochemistry and Geochronology Laboratory this past weekend! #ExploringTheCosmosSince1999
So @AstroDocScott & I are prepping for R2R @GrandCanyonNPS this fall (North Kaibab to Bright Angel in a day) — hiked up Sunrise Peak at dawn w/ temp in mid/high 90s! Not surprisingly there was hardly anyone on the trail! Looking for suggestions of other good hikes in PHX area.
