Slopes too steep to Balance on?

[kyrt-ryder]

Includes DCs to Balance on Slopes of greater than 45 degrees.

Climb includes a DC to climb up a slope 'too steep to walk up' but lacks any information on such a slope.

So... exactly what angle of slope requires a climb check? 60 degrees? 75?

[Starglim]

A surface angled greater than 60 degrees from horizontal is not a slope, but a wall (or could be a ladder, if it has footholds complete enough to call steps). Anything less appears to be at the GM or module designer's discretion.

Possibly a surface that is severely sloped (between 45 and 60 degrees, as per Acrobatics) and has inadequate footholds, such that it would have a Climb DC of 15 or more if it was a wall, is too steep to walk up.
