The high plains of Union County are anchored by the prominent rise of Sierra Grande, a massive volcanic feature that dominates the western portion of this landscape. In the shadow of this peak, the small settlements of Grande and Little Grande sit near the transition between the mountain slopes and the wide drainage basins of the northeast. The area is defined by its drainage networks, including the upper reaches of N Br Corrumpa Cr, S Br Corrumpa Cr, and Seneca Cr.
