An insane spell similar to Cascade of Rocks (Ars p.155) to chop a massive segment of hillside or mountain into small usable chunks. Moving them is another matter.
Pathway Through the Mountain
Perdo Terram 40, R: Touch, D: Momentary, T: Part
This spell tunnels through rock and earth to create a pathway as chosen by the caster, removing up to 100,000 cubic paces of material. This area is equivalent to a pathway 3 paces high and wide, and 5 miles long.
(Base 4, +1 Touch, +1 Part, +5 size, +1 flexible shape)
Carve Mountain into Rubble
Perdo Terram 45, R: Touch, D: Momentary, T: Part
Cuts the rock and earth in the shape chosen by the caster, equal to 1,000,000 cubic paces into cubic foot segments, likely ruining the stability of a large area and causing significant damage. This area is equivalent to a cube 100 paces to a side, or a dome 78 paces high and 157 paces wide at the base.
(Base 4, +1 Touch, +1 Part, +6 size, +1 flexible shape)
