New Comment: Vertically Challenged
by Bunsen7  1 Oct 2021
Looking at maps - a good way to plan a route and a cure for boredom. And my seemingly well crafted map says this is 604 metres high (shock/horror) and the col to the west is at 572m? Jesus, Mary, Joseph and the wee donkey. It's not on the "big lists".

So I turn to MV, and I see that this stops just 40cm short of the height required to join the VL list, and its prominence is 150cm too low to join the Arderin list.

40cm is fairly tight now it has to be said. Sure a big rock of granite could be lifted across and made look like it was there all along!

But I note the following

- It is marked as having a height of 599m on the 1:50k OSI map but 604m per East-West Map 2013.
- The historic 6 inch Black and White map from the 1840s has it down as 1972 feet (which is approx. 601m per google)
- The 6 inch Cassini had it down as 1975 feet.

I think this page thereby warrants a comment on the accurate measurement that must have been recently taken, assuming it is known to MV members! And for the sake of future generations, surely an unequivocal statement must be made by MV on the effects of changes in sea levels! (No doubt this statement is already on the website).

I also remember that sea levels are rising, and although the north of Ireland is rising as it rebounds from the suppression of the ice sheet from the last ice age, this has possibly of little or opposite effect on the South of Ireland

[ED: This was measured with a differential GPS, accurate to 10cm) in 2015. The heights given in MV are related to generally accepted datums. These were derived from low tide measurements and are provided by National Mapping Agencies. In due course these no doubt will be revised in the light of rising sealevels.] Linkback: https://mountainviews.ie/summit/1389/comment/23289/
