I had no idea about viewshed analysis in CalTopo, what a cool layer!bdloftin77 wrote: ↑Tue Mar 23, 2021 5:36 pmHere's what I found. I used Caltopo: 25 ft for View from Here, and 2 meters (about 6 ft standing height) for Viewshed Analysis. I didn't count the peak you're standing on, so visible + not visible should equal 57.
Harvard: Visible- 48 (barely visible: Sunshine and Wetterhorn. Wetterhorn barely visible in Viewshed Analy). Not visible: Longs, Chicago Basin group, Wilson group, Culebra (9)
Tabeguache: Visible- 48 (barely visible: Quandary in Viewshed Analy but NOT visible in View from Here though). Not visible: Longs, Holy Cross, Massive, Windom, Capitol, Wilson group, Culebra (9)
Princeton: Visible- 47 (barely visible: Quandary, N Maroon, Sunshine). Not visible: Longs, Oxford, Eolus, N Eolus, Sneffels, Maroon, Wilson group, Culebra (10)
Antero: Visible- 47 (barely visible: Handies and Quandary). Not visible: Longs, Holy Cross, Massive, Maroon, N Maroon, Snowmass, Wilson group, Culebra (10)
Shavano: Visible- 45 (barely visible: Snowmasss). Not visible: Longs, Holy Cross, Massive, Windom, Sunlight, Pyramid, Capitol, Quandary, Wilson group, Culebra (12)
Feel free to check my work! Especially those that are barely visible and those that are not visible. Longs, the Wilson group, and Culebra are not visible from any of the above summits. Being able to see both San Juan and all Sangre summits minus Culebra is very helpful for this area of Colorado.
If you subtract Quandary from Tabeguache's view (it's labeled in View from Here, but you can't actually see it rising above the Cameron/Lincoln saddle), then Harvard might be the winner at 48 14er summits visible.
Edit: Using this, it looks like the furthest visible from Denali is Alaskan 13er, Parka Peak, 266 miles away! Pretty cool to use this coupled with the range rings. I'm definitely going to spend some time playing with this on CO peaks today!
