We don't. Not in southern Britain, anyway. Britain's highest mountain is Ben Nevis, which is an extinct volcano and is 4,409ft above sea level (although there's a bit of a difference between highest mountain and tallest mountain).
One of the two men who died during a military exercise on the Brecon Beacons at the weekend has been named.
The Ministry of Defence has named the soldier as Lance Corporal Craig Roberts. He was trying out for the Territorial Army's SAS section.
The 24-year-old, originally from Penrhyn Bay, Conwy, and his fellow reservist died on the hottest day of the year in Wales.
Mr Roberts lived in London and was a maths teacher in Lewisham.
His father Kelvin, 53, and mother Margaret, 54, were said to be "heartbroken" by his death.
"We are being given the support of the military and anything we want to see will come through them," said his father.
Mr Roberts, who had lived in London after leaving university, had served with the Territorial Army (TA) for more than five years.
He had taken part in exercises several times including a training mission in Texas with the American National Guard.
Some of it involved hot weather training in the desert aimed at replicating conditions in the Middle East.
He was a member of the 3rd Battalion Royal Anglian Regiment and is believed to have served as a reservist in Iraq and Afghanistan.
L/Cpl Roberts was described as being "the salt of the earth" by friends.
"CJ loved being in the TA and really wanted to go as far as he could. He was extremely dedicated," said one.
Another soldier who died has not yet been named. A third man who collapsed remains in hospital.
