Mount Griggs is a stratovolcano near Novarupta, and somewhat to the northwest of the otherwise straight line of volcanoes in Katmai. The flat-topped mountain has three concentric craters, the largest wide. The mountain's geochemistry differs from its neighbors. Griggs has active sulfurous fumaroles. Snowy Mountain is a small volcano tall, with ten significant glaciers covering almost all of the mountain. Roughly a third to half of the mountain has been eroded by glacial action. The volcano has two vents about apart, and active fumaroles at the tallest summit. Mount Denison is a peak with four related vents at the head of three glaciers, the tallest point in the park. Mount Kukak is another ice-covered volcano, tall. It has a strong fumarole field near the summit. Devils Desk is a heavily eroded stratovolcano, high. Kaguyak is a stratovolcano truncated by a caldera, like Katmai. The highest peak is , with a diameter crater lake. There are two large domes within the caldera and two on the flanks. Mount Douglas is a stratovolcano, extensively eroded by ice, with a small acidic crater lake at its summit. Mount Steller is located between Kukak and Denison, with an unknown number of vents in ice-covered terrain. Kejulik is a eroded volcanic remnant. None of these volcanoes have exhibited significant behavior in historic times.
