A short distance further up the Valley and on the opposite side stands Sentinel Rock, the dominating landmark of the southern rim of the Valley, named by the Indians Loi-ya, or "water basket." Towering three thousand feet above the floor of the Valley, this magnificent column of granite, showing on its weather-worn face all shades of translucent grays and blues and mauves,
is doubly impressive in its splendid isolation, its calm dignity and nobility, its sheer glory of stalwart beauty.
