Mountain lions range throughout the Park. There are reliable sight
records of lions and lion tracks, but no specimen has been preserved.
Early records of observations include the report of tracks seen in
Navajo Canyon by Cary (1911:165), and a lion seen in 1917. Since 1930
the more adequate records include reports of from one to eight
observations each year for 26 of the 30 years. Young animals (recorded
as "half-grown") or cubs have been reported in four of these years. The
tabulation of dated reports by month beginning with January is: 2, 0, 3,
2, 8, 4, 6, 7, 4, 9, 5, 7. Mountain lions range more widely than bears
in their daily and seasonal activities, but like bears probably breed,
bear young, and feed in the Park. Although at any one time lions may or
may not be within the Park, it is part of their normal range and the
species should be regarded as resident and is not uncommon.
