Hasn't voted | It is probably a false claim (myth). This claim is widely used in official literature, but a number of people have disputed it. For example, Pikes peak is a highly qualified contender. Search google for "diablo kilimanjaro view". | |

Voted 10/10 | I think there is a quantitative way of determining such a measure. On a digital elevation model, simply trace straight rays at all (reasonable) azimuths and elevations from the summit of interest to obtain a map like this: Half Dome. Of course, this approach ignores haze and other atmospheric events (curving rays), and also ignores the earth's curvature (easy to correct for) but you get a pretty good idea of what's going on. | |

Hasn't voted | Morgan, very nice exercise. You can calculate visibility areas with a standard GIS software like ArcInfo. However, the crux of the problem is obtaining enough digital elevation model data to cover all visible areas. This is very difficult as the visible areas can be 200+ miles in radius, which means a high resolution dataset of the area will be huge. Using a smaller dataset you'll always miss a few distant peaks. | |

Hasn't voted | Yes, these are endemic plants on Mt Diablo; the names of quite a few native plants carry the name of the mountain. | |

Hasn't voted | Gordon, I've heard the claim before that Diablo has one of the country's farther ranging views. Hadn't heard the bit about it being only 2nd to Kiliminjaro. How is that determined, or from which sources did you get that (not disputing your claim, merely curious)? | |

Hasn't voted | Unless there's another Mt Diablo nearby, this mountain is in the news this week as the home of the thought-to-be-extinct Mount Diablo Buckwheat | |

| Scott Fulton | Summit Trail closed on 7/2/06 | |
Hasn't voted | As of July 2nd, 2006, the Summit Trail was closed at the South Gate Entrance due to landslides. There was a barrier about 200 or 300 yards from the trailhead. I'll try again later this summer, but I'll call the Park beforehand. | |
