As all the scenic Parks are in high mountain country, the tourist
should be sure to wear warm clothing suitable for rough outdoor use.
Woolen trousers or riding-breeches are desirable, not only because of
their warmth, but also because they offer better protection in rainy
weather. Woolen underwear is recommended because it prevents the body
from becoming chilled when a rest is taken when the climber is
perspiring; nothing is more uncomfortable or dangerous than cotton
underwear wet with perspiration. Women who expect to climb should wear
riding-breeches, as bloomers get caught on bushes and offer too much
resistance to the wind. A flannel middy blouse allows free use of the
arms and body and is far superior to the shirt-waist. A felt hat is
best for both men and women; it may be pulled over the eyes as a
protection from the sun, and it is far superior to a cap during a
rainstorm. Heavy, comfortable shoes and woolen socks or stockings are
essential for those who are going to tramp. Wet shoes may be worn if
the socks are dry; the shoes will feel cold and clammy at first, but
a little brisk tramping will soon make the feet warm and comfortable.
Motorists should bear in mind that the high altitude causes a marked
reduction in the power of the engine, so that much more gasoline will
be required than at sea-level. Care should be taken that the engine
does not become heated on long grades.
