贡嘎主峰与海螺沟冰川 / Gongga summit and Hailuogou Glacier

Coverage: 101.726°–102.046° E, 29.510°–29.693° N. North is up. Coordinates are shown on a local equirectangular grid with longitude scaled at 29.60° N. The scale bar spans 5 km at this latitude. Smooth hillshade and 250 m elevation contours were computed from the DEM. The glacier point identifies its general location and does not represent a terminus or boundary.
