Mount Crickmer is one of the southernmost summits of the Garibaldi Ranges of the Coast Mountains, overlooking the Central Fraser Valley in the Lower Mainland of British Columbia, Canada. Forming a rocky knoll at the northern end of a relatively flat-topped southeast-northwest axis ridge named Blue Mountain, which divides the basin of Alouette Lake, which lies immediately below it to the west, and the valley of the Stave River; Stave Lake is immediately at its eastern foot. A northerly ridge towards Mount Robie Reid, the next summit northwards, forms a col at Florence and Morgan Lakes low enough to give Crickmer a considerable prominence of 1049m. Beneath that col there is a diversion tunnel feeding the waters of Alouette Lake to the Alouette Powerhouse on Stave Lake.
