Anyone have the web link to the peak view calculation website that we have used in the forum before? Shows a graphic of what can be viewed from specific locations. Recall someone showed where in the San Joaquin Valley that Half Dome was visible from on clear days.

Dave,

I'm not sure if this helps, but if you scroll through the comments, some gps coordinates and other things are called out.

To add more, if you go to cal topo and click a point and "Add new layer" and do the viewshed analysis and it will show you what is viewable form those points. (took me a minute to remember that way)

Hey cslaght -

That's some cool stuff. As a long time caltopo user, I didn't know it had that capability, so I appreciate the new knowledge from you. Thanks for posting it up. :)

Thanks Shawn and cslaght,

Recall seeing both those tools in the past but had not read documentation to use them. So first tried the peakfinder tool but had a difficult time making sense of how it actually correlated to my below photo without playing with Google Earth at the same time. It is a cell phone app and the feature and control set are straightforward seeming to be oriented to peakbaggers.

The caltopo tool is a more comprehensive desktop pc tool that I had to explore some before making sense of its use. Per the image below was able to reasonably duplicate the tool's graphic to my actual photo. That is a June 15 view a bit north of due east from the east shoulder of Mercur Peak at 7900 feet. To figure out the annotated points, I had to use Google Earth and the acmemapper topo views.
