Malpais National Monument—where sharp lava meets smooth
sandstone—is a large natural area south of Grants, NM. A huge lava
flow fills most of the wide valley. The combination of aa
and pahoehoe lava makes foot travel difficult, but the Continental
Divide Trail crosses through the area. We hiked a couple of miles on
the CDT as well as enjoying sandstone features such as the Sandstone
Bluffs Overlook and La
Ventana Natural Arch.
