Peter Bay is a small inlet at the foot of the Koryak Mountain range well north of the Kamchatka Peninsula. At the entrance of the bay is a Largha seal haul-out site and a small hidden lagoon flanked by the ocean and the bay. The southern end of the bay has several small lakes that are dammed behind a moraine ridge; the remnant of an ancient glacier. The lakes feed a spectacular waterfall. The western and eastern sides of the bay have steep cliffs that seabirds favor for nesting sites. Their busy comings and goings from nest to ocean feeding grounds punctuate this Far Eastern Russian location.
