There are parts of the FAA "Mountainous region" that are at or even below sea level. Its a blanket approach.
The only people that will want to know actual mountain hours are the government (usfs/doi...) or an operator that has or wants to get a contract with the government. As stated above i don't have the exact numbers in front of me but it something like numerous takeoffs/landings above 7K'+ to include pinacles, saddles etc. Cruise flight at 8k' doesn't count.
