The American Elk
The American Elk or Wapiti, a member of the deer
family, is the largest mammal in Rocky Mountain National Park. It is as
majestic as it is large. There are few sights finer in the wilderness
than a great bull with his full set of antlers, and there are few sounds
that thrill the listener more than the clear, challenging bugle of the
males as it rings through the frosty air, inviting all those who doubt
his supremacy to battle.
The antlers are truly the crowning glory of this
great animal. It is hard for many to realise that these large beams grow
in a single year, but such is the case. In February, after all possible
chance of combat is over, the antlers are broken or rubbed off at the
base. Almost immediately the new growth begins, first as a red swelling
which resembles a tomato, and later as a long protrubance which
eventually branch. At this time the new antler is soft and tender and is
richly supplied with nerves and blood vessels. It is covered with a
thick coat of silky hair known as "the velvet." Long before fall the
antlers harden, the velvet is rubbed off and the points are sharp and
shiny for the fighting season. It is often said that the age of an elk
can be told by the number of points on his antlers. This is not always
the case, for often, after seven or eight years the animal ceases to add
points.
The elk is the most polygamous of all the deer. A
large elk bull usually has a harem of cows during the mating season, and
it is often necessary for him to fight in order to uphold his position
among them. These wilderness battles often end in tragedy, for it is not
uncommon to find the skeletons of two great bulls that have died of
starvation as a result of the antlers becoming locked during such a
fight.
The calves are born in May and are spindle-legged
little creatures for the first few days. They are spotted like the fawns
of the deer and are cared for in much the same way by the mother.
Usually one calf is born, two being much more unusual than it is with
the Mule Deer.
As was the case in so many other localities, the
native elk were practically exterminated in this region. About 1912,
however, a small herd of 25 animals was imported from Yellowstone Park.
The following year another herd was brought in. Some died, hut others
drifted into the interior of the park and multiplied until in 1932 it is
estimated that 446 elk range within the boundaries.

The 1932 Educational Program
This summer will see an enlarged educational program
in Rocky Mountain National Park. With the addition to the staff of Mr.
Dean Cornwall of the Geology Department of Oklahoma University, with two
seasons of Yellowstone experience and Mr. Bert Frasier who will begin
his fourth season in the park, our visitors are assured of a
satisfactory and well rounded program.
At the present time 144 lectures, mostly illustrated
are scheduled as well as 132 field trips. In addition to these, auto
caravans, long field trips, museum and self-guiding nature trails will
augment the program.
Of special interest is the initiation of all-day
Saturday trips and the four day trip beginning on August 6th which will
be conduct(ed) through some of the most spectacular country in the
park.
A complete schedule of trips will be furnished on
request, or the week's schedule can be procured at the Museum. We
cordially invite not only our readers, but all of our visitors to hit
the trails with us this summer.

Growth of Antlers
It occurs to us that the following information
relative to the growth of deer antlers will be of interest to our
readers. The quotation is taken from a recent statement by Dr. Joseph
Dixon, Field Naturalist for the National Park Service.
"Exact age can not be told by antlers in mule deer.
The popular notion that a buck adds one prong or point to his antlers
each year has been shown not to be true. In the Modoc region of
California yearling mule deer bucks often have their first set of
antlers forked-horn while in central and southern California the first
antlers are spikes.
"In Yosemite, the following is the normal antler
production:
1st yearspike.
2nd yearforked-horn.
3rd year3-point (eye guard or brow tine acquired.)
4th to 8th yearsnormal 4-point.
8th to 10th yearsextra points may or may not be added."
