5.
Picabo is located about north of the Snake River along the northern edge of the Snake River Plain, a topographic depression that cuts across the Basin and Range Mountain structures of southern Idaho.

The accumulation of dense nitrogen ice would have contributed to making Sputnik Planitia a positive gravity anomaly, but by itself would not have been sufficient to overcome the topographic depression associated with the basin.

The largest single expanse of the smooth plains material surrounds the Caloris Basin mostly in Tir and Budh Planitiae but many smaller patches occur in crater floors and other topographic depressions within the heavily cratered terrain in the southeastern part of the quadrangle.
