Having lived in Yosemite for 14 years, I developed a good sense for what the weather is up to. But when teaching workshops, like I did last month, it can be advantageous to know a little more certainly what is up for sunset. This could mean sending an assistant up to a high vantage point for a look-see to the west. When the non-profit Yosemite Association chose to reorientate the webcamera on top of Turtleback Dome 180 degrees to point west toward the setting sun, rather than east toward Half Dome they saved us the time and gas for the trip. Combined with satellite imagery of weather systems on the major weather websites, it is now possible to be in a wifi hotspot or the Ansel Adams Gallery in the early afternoon and see what the cloud cover and weather conditions are to the west to plan movements for the remainder of the day. While not a slam dunk, it does improve the odds for gauging the potential for magic light on the valley icons without driving all the way up to Turtleback. With four cameras at different elevations, it is also much easier to see what the current snow level is. Check it out yourself at www.yosemite.org.
