Show 25 30. Greeley Hill ( Figure 23) Moderate intermittent hazard. Controlled from the Albion gun or from the road with the pack howitzer. Although this slope does not slide very often, a particular hazard exists on it; ie., if a person is caught in an avalanche here, he most likely will be carried into Snakepit - a permanently closed, steep- walled gully immediately below. It is, therefore, very important that control work be carried out regularly on it. During some years, depth hoar forms on this slope, particularly on the portion of the slope with a more northern exposure. 31. Snakepit ( Figure 23) High intermittent hazard. This very dangerous, steep-walled gully is located directly below Greeley Hill. Anyone skiing into this area and caught by an avalanche is very likely to be buried deeply in the bottom of the gully. Though the slope is not long, the gully's bottom is very narrow, allowing no outrun for an avalanche. When Greeley Hill slides, it can deposit a tremendous amount of snow here. Control is by permanent closure, but it is also necessary to shoot it with the pack howitzer often to guard against the possibility of someone violating the closure and getting himself into danger. |
