has panos from Charleston Peak, Mount Whitney, Mount Diablo, Mount Washington (NH), and a few others. But we do need more American representation on that site...... It also has a gallery of panos with their photo counterparts alongside (like the 221 mile view to Denali from Sanford).
is a great site to generate American panorama viewsheds. Outside the USA, it's somewhat less accurate, but I've still used it to get a general idea of what other countries might have. Basically, you make sure the cursor is pinpointed over the highest part of the mountain (perhaps substitute the actual elevation at times), then generate it.
My hope is that we can get a whole bunch of stuff up and begin comparing actual photos with what these two websites can generate.......
I'll throw out some line of sight challenges for us Americans to photograph, based on my research:
1. In the East, Camel's Hump in VT is intervisible with Black Dome Mountain in the Catskills, just over 150 miles away. We need a pic of this.
2. Mount LeConte, in the Smokies, from Garden Mtn, VA - about 150 miles, this is the longest Southeast USA view I've discovered to date.
3. From the Colorado Plateau, Utah - the Fish Lake Hightop complex (including Terrill, Marvine, and Hilgard) to Mount Wilson in the San Juans (about 200 miles). This may be the longest American Rockies view.
4. Sierra Blanca, NM, to Truchas Peak in the Sangres (about 185 miles). Lots of good long range views from that one.
5. Good one: Devil's Tower, WY from Cloud Peak in the Bighorns. That would be neat to capture (with a REALLY big zoom lens!). By the way, Cloud Peak in general has one of the longest viewsheds in the American Rockies, because of its isolation.
The Cascade volcanoes win the biggest prize in the lower 48 simply because of their height and isolation. If we can nab a pic of Rainier from the Wallowas, that will in all likelihood be the unbeatable one for line-of-sight. But really anything above 150 miles is superb.
Let's try to get some of the experts on here as well as some more pics. Thanks again for all the suggestions so far!
