Forgive my flatlander stupidity.

Not all elevation is created equal.

On trail or off trail?

Blowdowns?

Shale?

Underbrush?

Basalt cliffs in the mix?

Starting elevation?

I do a training hike that is 800 feet gain in 0.2 miles. It's STEEP. 1k in 1/2 mile is going to be a pretty decent hump. However, if that's all I need t climb and then I'm hunting a plateau, no big deal. Do I need to drop off the other side? Do need to climb higher? Also, I find GE tends to make things look a little flatter than they always end up being in reality. I always cross reference with topos.

better go get your construction master. It's way steeper than a 5/12 pitch. 1k feet in half a mile is 1000/2640 or 1/2.64 feet or 37.84%

Take 1000 feet and divide it by 2690, multiple by 100%. It's 34% slope.

A 5/12 pitch roof is actually a little steeper at 42% slope. Divide 5 by12, then multiple by 100%. It's 42 percent. A 6/12 is dead at 45%. a 7/12 is 59%. Etc...




I've carried and nailed on over 500 roof full of shingles in the last 25 years. I don't truly know the total squares of shingles that is. If not for metal roofing, that number could likely be tripled and still be right. I don't miss it one little bit either. God Bless men

2640 is a half mile, otherwise pretty spot on. Not sure how he came up with 5/12 being a little over 20% slope. I need to quit doing any kind of math at 2am lol.

Yep, I don't know where I came up with 2690 at?

Not to sidetrack further, but a roof with 12' of rise over 12' of run (or 12/12) is a 45 deg pitch.

And some more perspective, anything over 35-40 degrees is a black diamond ski slope with 50 degrees being about as steep as they get.

And most avalanche slopes are between 33-37 degrees. Anything steeper than that doesn't hold enough snow to slide.

Good post here.

I'll stand by the fact that it's a 4-9/16" in 12" roof pitch, 20.75 degrees roof pitch, didn't say anything about percentage of slope witch would be 38 percent. I was just trying to give the guys a reference for steepness, if in fact it was a even incline, witch never is.

Thanks for the help guys. Starting to like this place.

We haven't even discussed WTH your boots will be doing to your feet on the downhill trek, how your lightheadedness at 11,000' will make you more likely to fall down or what you'll think when some marathon runner flies by you at light speed wearing something that looks like a wife beater tee and yoga shorts.
