Drove to Logan Pass on the Continental Divide. Hiked from visitors center to Hidden Lake overlook, then proceeded down to the lake, took a lunch break and headed back up as the weather changed to hail and gusty winds. A grizzly bear and her two cubs were sighted by other hikers, but we were too late to catch a glimpse of them. We did, however, spot two hoary marmots. Continued down the Going to the Sun Road to St. Mary. Stopped along the way to view Jackson Glacier.
