It is presumed that those seen over the lake are nesting somewhere about the Rim. The Castle Crest Wild Flower Garden, which has been developed with a path displaying to best advantage the various habitats in which the variety of wild flowers grow in particular profusion has been visited daily by a large number of tourists. When this new feature becomes more generally known it will undoubtedly attract considerable attention. Other than being a wild flower garden it has proved to be among the best places in which to observe Park animals. Where the trail passed under talus lying at the foot of Castle Crest, the visitor is invariably greeted by whistles of conies from the rocks above.
Marmots are particularly numerous.
It is related by one visitor that he saw an older marmot hurriedly covering several younger ones with earth at his approach. The grass and flowers upon a moist slope were crushed as by the weight of some heavy object passing down the slope. A workman clearing the trail reports that he observed the bears descending this hill, sliding through grasses into the meadow below. Of the birds, many species not common on the Rim are to be found. The Gray Jay, Stellar's Jay, and Clarke's Crow are common, the Warblers of many species are numerous, the Creepers, Nuthatches, and Robins are seen or heard daily.
