Move Earth

When cast, the move earth spell moves dirt (clay, loam, sand) and its other components. 

Thus, embankments con be collapsed, hillocks moved, dunes shifted, etc. The area to be affected will dictate the casting time; for every 4" square area, 1 turn of casting time is required. If terrain features are to be moved — as compared to simply caving in banks or walls of earth — it is necessary that an earth elemental be subsequently summoned to assist. 

All spell casting and/or summoning must be completed before any effects occur. In no event can rock prominences be collapsed or moved. 

The material components for this spell are a mixture of soils (clay, loam, sand) in a small bag, and an iron blade.

The practical limitation on the area of effect of this spell is a 24" square area, with four hours of casting time, exclusive of elemental conjuration.
