Pinus rigida
Pinus pungens
Pinus rigida often has poor form and is not valued highly as saw timber. It is fire successional, sprouts adventitiously, and is frequently shrubby in the northern part of its range. It is known to hybridize naturally with P. echinata.

Pinus pungens is a scrub pine and is too small and knotty to be much utilized except for pulpwood and firewood. Its common name refers to a general type of landform, not to a specific, named mountain.
