message: On talk page I can loosen my tongue a bit. The claim that there is more viewable area from Diablo than anywhere else except Kilimanjaro is commercially motivated. Viewfinder 18:13, 12 November 2005 (UTC)
replies: text:  I am aware of atmospheric refraction and take it into account. Under normal atmospheric conditions Mount Shasta is not visible from Mount Diablo. But if there is a major atmospheric temperature inversion, the effect of refraction can increase, and this may, just possibly, allow Mount Shasta to be seen. But its distance is 242 miles, so the atmosphere would also have to be exceptionally clear. Viewfinder 05:55, 20 January 2006 (UTC)

message: I have failed the GA request.  For one, there is a severe lack of inline citations, which is an absolute must.  Second, there has to be significant cleanup regarding the links and prose, especially in the areas where it's just paragraphs of names and species.  I suggest cleaning this article up significantly and attempting a peer review before nominating it again.  Good luck! --badlydrawnjeff talk 18:41, 28 November 2006 (UTC)

message: The Peakbagger citation states that the summit of Mount Diablo is the highest point in Contra Costa County. It's late and I couldn't see and easy place to fit this in. --droll [chat] 07:40, 29 June 2009 (UTC)
thread_title:  High point 

message: In the "Claims on viewable area" section, it says:
According to a sign at the summit, it is possible to view the second greatest surface area seen from any peak in the world.
I was at the visitor center earlier today and although unfortunately I didn't study all the signage carefully or take a photo of the main sign that discusses this, I am almost certain it did not make this claim.  I can believe it once did, but given the thorough debunking this claim has been given, I can also believe that the sign would now be changed to soften this claim.
Can someone say definitively that A) there used to be such a sign, and that B) there no longer is? Thanks, NapoliRoma (talk) 08:34, 1 January 2010 (UTC)

message: The snowfall numbers are very confusing. Is the maximum snowfall on the mountain 3 (1972) or 6 (1975) or 18 (2009) inches? If one or more of these numbers is for the maximum depth on the ground (even though more may have fallen and melted) this should be stated more clearly.  Much of the climage information could be deleted or at least summarized down to be smaller.  Sanpitch (talk) 23:56, 24 September 2011 (UTC)

message: To clarify, realizing it is outside of the MDC see Strava.  While it shows Mr English at #5, it shows that the Tour of California had several riders besting that time.  The fastest shown is by pro racer Marc de Maar on May 18 2013.  The top 10 fastest shown are all from the Tour of California stage race.--Billymac00 (talk) 13:33, 4 July 2014 (UTC)

message: I'm citing: 
http://cowellhistoricalsociety.org/html/devil.html
: One of the more interesting legends about the mountain is that told by General Mariano Vallejo in his April 16, 1850 report to the California Legislature. He gave the following report on the origin of Mount Diablo’s name in its Spanish form:
::In 1806 a military expedition from San Francisco marched against the tribe “Bolgones,” who were encamped at the foot of the mount; the Indians were prepared to receive the expedition, and a hot engagement ensued in the large hollow fronting the western side of the mount; as the victory was about to be decided in favor of the Indians, an unknown personages decorated with the most extraordinary plumage, and making divers movements, suddenly appeared near the combatants. The Indians were victorious, and the incognito (puy) departed toward the mount. The defeated soldiers, on ascertaining that the spirit went through the same ceremony daily and at all hours, named the mount “Diablo”, in allusion to its mysterious inhabitant, that continued thus to make his appearance until the tribe was subdued by troops in the command of Lieutenant Gabriel Moraga, in a second campaign of the same year. In the aboriginal tongue “puy” signifies “evil spirit,” in Spanish it means “diablo” and doubtless it signifies “devil” in the Anglo-American language.
Note that there is no report here of any "flying, spectral apparition" as mentioned in the current Wiki text.

thread_title: An inselberg or monadnock ?

message: The article states, "...more interesting than the sunset itself is the view of the progression of the mountain's shadow across the California Central Valley to the distant Sierra Nevada..."
     My recollection is that the sun sets in the west, hence the shadow of the mountain would be towards the east: San Francisco Bay, the Santa Cruz mountains, and the Pacific Ocean.  (Is the Pacific visible from the summit?)  The shadow of the mountain would fall to the west during sunrise; perhaps that's what the writer meant.  — Preceding unsigned comment added by 2601:646:8B82:FEB3:843F:157D:FAFE:4E06 (talk) 04:19, 28 August 2017 (UTC)
replies: text: The text as written is correct. The shadow falls in the opposite direction of the light source. The Sun sets in the west. Therefore the shadows fall to the east. Mount Diablo is east of the San Francisco Bay, the Santa Cruz mountains, and the Pacific Ocean, so the shadow cannot fall on them - as they are to the west.
