Fort Glenn was constructed to protect Dutch Harbor on neighbouring Unalaska Island from Japanese attacks. The only settlement on the northern part of the Island is a cattle ranch. Here the main ranch house. On the left the slaughterhouse. During the summer months, the cowboys are doing their work, like gathering cattle.
Horses are an important means of transportation on the island.
But ATV's are not bad either. Here I get a ride with Pat, the manager of the ranch, to Okmok Caldera, with some of my GPS equipment in the little trailer. In the summer 2000, we started making more sophisticated GPS measurements around Okmok volcano to investigate its deformation. Our base was again the ranch in Fort Glenn. Logistics are not always easy in the Aleutians, and before we could get started with the scientific program, there was some hard work to do.
