What is the criteria for inclusion on this list? There are several peaks which are part of the Semien Mountains that are not in the section "Ethiopian highlands". -- llywrch (talk) 17:37, 10 August 2009 (UTC)
- I would assume that that is because their topographic prominence is less than 1500 metres. Or have we missed something? Viewfinder (talk) 04:58, 11 August 2009 (UTC)
Socotra's highest peak
editThis list lacks Socotra's highest peak of 1503 m --Jakas1 (talk) 11:03, 9 February 2010 (UTC)
- Socotra belongs to Yemen and is therefore listed at List_of_Ultras_of_West_Asia#Gulf_of_Aden. Personally I would rather lists of mountains by topographic prominence were listed geographically rather than politically, and list Socotra under Africa. Viewfinder (talk) 09:12, 5 November 2016 (UTC)
Batu and Tullu Deemtu in the Ethiopian Highlands section
editThe data for the second peak listed in this section, Batu, is actually for a nearby peak named Tullu Deemtu. Peaklist.org confirms this in its list[1] and in that page's number 14 footnote[2]. I will make the change on this page now.--Racerx11 (talk) 03:46, 15 January 2012 (UTC)
- Done. Also edited my above comment, fixing the wikilink to Mount Batu.--Racerx11 (talk) 03:52, 15 January 2012 (UTC)
Canary Islands?
editWhat about the Canary Islands? They're African too and they have mount Teide higher than 3700 meters. 87.221.188.120 (talk) 17:56, 2 May 2014 (UTC)
Cherang'any Hills
editShadychiri did well to add the highest point of this range to this list. But it is possible to draw a line from this point to 4,001 meter Mount Satima, which goes no lower than 2,009 meters. Therefore the prominence of the Cherang'any HP is 1,515 meters. Viewfinder (talk) 20:39, 2 November 2016 (UTC) Viewfinder
- (talk) Thank you for your inquiry. Mt. Satima is on the other side of a prominent geological feature that is the Gregory Rift Furthermore, the two are far apart the other being in near Mt Kenya while the other being adjacent to Mt Elgon a separation of close to 300Km.
- Please study the definition of topographic prominence. It is about drop, not distance. Cherang'any and Satima are connected to each other by a long, broad ridge that does not drop below 2000 metres. Viewfinder (talk) 17:26, 4 November 2016 (UTC)
- Its More Appropriate to have its prominent peak as Mt. Elgon. Until Further Evaluation of the Issues Raised, I think its Appropriate to remove the hills from the list of Ultra's Shadychiri (talk) 18:36, 7 November 2016 (UTC)

- Shadychiri, if the sea level were to rise to between 1900 and 2000 metres higher than its present level, Cherang'any and Satima would be on the same island, but Elgon would be on a separate island. Prominence is about these hard facts, not what you think is appropriate. But for as long as you continue to contest the prominence and parent of Cherang'any, and they have not been verified by other researchers, then as far as Wikipedia is concerned they are my original research and I cannot continue to contest them here.

- Viefinder if the sealevel where to rise to the said level, the two (Mount Satima and Cherang'any Hills) will be divided by the even lower Gregory Rift which has average floor level at 1600 masl. Shadychiri (talk) 14:51, 8 November 2016 (UTC)

- Not correct, there is a shoulder across the rift which can be crossed without dropping below 2009m (at S 0:29:51 E 36:18:51). Still, until other researchers have checked out the situation for themselves, there seems little point in continuing this discussion. Viewfinder (talk) 16:09, 8 November 2016 (UTC)
Hi, I have carefully considered the situation discussed by following the relevant contour lines (the 2000 meter range). It seems clear that key prominence saddle defining this prominence, is in the 2000-2020 range. Thus, the information by Viewfinder is correct. I have a genuine interest in getting this information correct since I am among the people (worldwide) that has climbed more than 200 ultra prominent mountains (see Peakbagger.com), I am currently in the planning phase of making a trip to Tanzania/Kenya.P2469 (talk) 22:40, 9 January 2017 (UTC)
