Mixed Grade:

These routes require considerable dry tooling (modern ice tools used on bare rock) and are climbed in crampons; actual ice is optional but some ice is usually involved.

M1-3: Easy. Low angle; usually no tools.
M4: Slabby to vertical with some technical dry tooling.
M5: Some sustained vertical dry tooling.
M6: Vertical to overhanging with difficult dry tooling.
M7: Overhanging; powerful and technical dry tooling; less than 10m of hard climbing.
M8: Some nearly horizontal overhangs requiring very powerful and technical dry tooling; bouldery or longer cruxes than M7.
M9: Either continuously vertical or slightly overhanging with marginal or technical holds, or a juggy roof of 2 to 3 body lengths.
M10: At least 10 meters of horizontal rock or 30 meters of overhanging dry tooling with powerful moves and no rests.
M11: A ropelength of overhanging gymnastic climbing, or up to 15 meters of roof.
M12: M11 with bouldery, dynamic moves and tenuous technical holds.
