Arapahoe Basin will expand its terrain to the summit for top to bottom skiing starting Wednesday, the ski area announced Tuesday. With the natural snowfall last week combined with the extremely good progress being made by the snow makers, A-Basin will open two additional intermediate runs, Lenawee Face and Dercum's Gulch serviced by the Lenawee Mountain Lift.

After the upper mountain has been opened, the ski area reports it will move snowmaking resources to Sundance and open that as soon as possible, opening more beginner terrain.
