It's only a 32 degree angle.

You could certainly walk up it fine.

Citation needed for sure and the authorities must have never encouraged it and I'm not sure why it'd be super fun to slide down but given the popularity of hiking, rock climbing, sledding, skiing, and snowboard it's totally logical people would want to go up and down it it.

32 degrees seems really really shallow compared to what I see in pictures. This source https://www.pbs.org/wgbh/nova/pyramid/geometry/angle.html says it's 51.5 degrees.

I was going to say it might depend whether the angle is measured along the middle of a face or along an edge, but with a face angle of 51.5 degrees I calculate an edge angle of 41.6 degrees.

That's assuming I still know how to trig, and it's entirely possible I don't.

Middle of the face, and probably more like 51.8° originally. That corresponds to base faces measured in turns of a measuring wheel and a height of the same number of wheel diameters, which would be an incredibly sensible way of laying it out (letting the tools do the calculation for you).
