Yoho Valley in this Park was not discovered until 1897, but its unusual beauty at once attracted numerous visitors. Takakkaw Fall is the thunderous spray-shrouded leap of eleven hundred feet of a glacier torrent. The Indian name means "It is Wonderful." This valley also possesses other beautiful falls, a remarkable ice region, and other interesting alpine features. Emerald Lake, admired by artists and nature-lovers, is said to have twenty shades of green, but never one of blue, in its crystalline mirror depths. It is reached by a straight road through dark fragrant firs that meet overhead. A dazzling white mountain at the end of the vista gave rise to the name Snowpeak Avenue. The Natural Bridge is not far from Field, the main-line railway town that serves as a center for this national playground. The Kickinghorse River forces its way through a narrow gap in a solid wall of rock. Rocks remaining above this boiling, seething mass of water and cloud spray make a natural passageway across and give the formation its name. Millions of trilobites have been found in the extensive fossil-bed of Mount Stephen. This probably was once the bed of an ocean. This massive, round-topped mountain, 10,523 feet high and with curiously marked sides, is probably the most frequently climbed peak in Canada. It seems to rise directly over the town, is not difficult to ascend, and affords wonderful views of the "frozen sea" of snow peaks to the north and west. 4. WATERTON LAKES PARK Waterton Lakes Park, in southern Alberta, is notable chiefly for its glacier lakes. Although one of the smallest, it is one of the most beautiful of the Canadian scenic reservations. Since sixteen square miles were set aside in 1895, it has been enlarged to four hundred and twenty-three square miles. For about twenty miles this Dominion playground adjoins the Glacier National Park of the United States. The two will be linked by a motor road, so that visitors to one may also enjoy the other. An enlargement of the Waterton River forms the main chain of lakes. The upper one, nine and a half miles long, extends three miles into the United States. Prehistoric glaciers gouged out the main valleys, leaving them carved in massive proportions. Beautiful streams rush down cañons, plunge in shining cascades, or remain dammed up as superb lakes. The lower valleys are clothed with forests. Columnar peaks, fantastic rock formations, and unscalable precipices complete the imposing effects. Fishing is a leading attraction. The Park contains many Rocky Mountain goats and bighorn sheep. Grizzly and black bears and mountain lions also are frequently found. 5. REVELSTOKE PARK
