Figure 71.January 1957.
Age: 9 years.

Figure 72.August 1958.
Age: 10 years.

Figure 73.July 1959. Age:
11 years.

Figure 74.April 1960. Age:
12 years.

Figure 75.January 1961.
Age 1 years. Note that beginning in 1957 at 9 years, no new
light-colored annual rings has matured, so that now in 1961 the dark
"ring" at the base of the horn is actually composed of five narrow dark
rings, each indicating a year's growth. This is typical of desert
bighorn ram development.

Figure 76.As we left in
1961, the Old Man followed along the fence, bleating. We were reminded
that he was 13 years old and that his teeth were going now and that when
we came another year things might not be the same. For things will not
be the same there againwhen the Old Man is gone.

Figure 77.Predictions were
made in 1937 that wild burros would drive the bighorn away from Lost
Spring. But the 1960 observations of the authors, and this 1961
photograph by Park Naturalist Ro Wauer, indicate that bighorn and burros
have shared this water without apparent friction for a quarter of a
century.
