The slide was at Shed 4 which was an old burned out snow shed. The slide came down on the west end of the old snow shed area. This was a rain over snow event. The slide was discovered because it tripped the detection wire above the track. Snow removal equipment is now clearing the track. | - | - |

These avalanches buried a portion of U.S. Highway 2 (US2) approximately four miles east of the village of Essex, Montana, as well as the mainline tracks of the Burlington Northern and Sante Fe Railroad (BNRR). US2 is the only east-west link across the Rockies in northern Montana; when closed, a 180-mile detour from East Glacier Park to West Glacier is required. US2 was closed during the evening of February 8 and into the morning of February 9 by snow avalanches blocking traffic. Additionally, approximately 75 yards of track of the BNRR were blocked for about eight hours, shutting down all freight traffic as well as the eastbound Amtrak passenger train from Seattle to Chicago. Notes from 2-21-96: Goat Lick Channel no avalanche, south-facing slope nearly bare of snow.Snow deposit of big balls that oozed slowly onto highway. Ripped out lots of trees. Fresh soil and snow pushed out to side by avalanche deposit, into flanking rampart on right side.

These avalanches buried a portion of U.S. Highway 2 (US2) approximately four miles east of the village of Essex, Montana, as well as the mainline tracks of the Burlington Northern and Sante Fe Railroad (BNRR). US2 is the only east-west link across the Rockies in northern Montana; when closed, a 180-mile detour from East Glacier Park to West Glacier is required. US2 was closed during the evening of February 8 and into the morning of February 9 by snow avalanches blocking traffic. Additionally, approximately 75 yards of track of the BNRR were blocked for about eight hours, shutting down all freight traffic as well as the eastbound Amtrak passenger train from Seattle to Chicago. From 2-23-96 notes Talked with BN Roadmaster, said snow ava. put 75 yds of snow under shed [7] on tracks and it took 2 bulldozers working 7 hours to get the BN line open. Both tracks in the snowshed were buried.the avalanche deposit. Very bally, slushy wet-snow avalanche from right hand chute. In fact, it came from a slab fracture, about 75-100m long, in the upper left steep part of the right-hand chute GCAC advisory 2-16-96: There was a tremendous amount of avalanche activity last week as a result of the new snow loading and heavy rain we experienced Tuesday-ThursdayMuch larger slides occurred on Java along the Middle Fork at Bear Creek | - | - |

Part of it flowed around and over the south end of the new bridge, leaving 24.2 feet of debris on the south end of the bridge. There was no debris on the north part of the bridge. The bridge was undamaged. The concrete Jersey barrier on the east side of the bridge near the southern abutment was cracked and pushed slightly out of alignment.This avalanche started at an elevation of 7,200-7,300 feet in area 1. The fracture face was estimated to be 4 feet tall except for a short distance in the southeast corner of the starting zone where it was 10-12 feet tall in a snow deposition area. Only about 40 acres of the starting zone contributed to the avalanche. Although fresh debris was present in starting zones 3, 7 and 9, none of this entered the main channel. (Martinelli) Highway 2 closed at new Goat Lick Bridge by avalanche debris covering 1,000 feet of highway with depths varying between 20 to 25 feet.

The inside rails were not blocked by broken timbers so the tracks were open for trains. Thursday morning [Jan. 10th] there were any number of trucks and cars lined up waiting for the crews to get the road open when another slide came down between them and Java so they were penned in between the two slides that day.

In the Essex, Java (Nimrod) and Fielding area, bridges had been swept from their locations and deposited against the opposite side of the valley. It amazed me that the Great Northern (now Burlington Northern) railroad had been able to keep their tracks open through all of this. All the way through the mountains from Belton (West Glacier) to East Glacier Park there were snow sheds, miles of them, protecting the tracks from these avalanches. Also, in many places were long tunnels. p.124 near Bear Creek this side of the continental divide where in the mid-1930s a slide moved a whole new concrete bridge more than 100 feet. | - | - |

(Panebaker) The whole slope from Sheilds Creek to Tunnel 11/2 is a troublesome one and following the accident to Train No. 27 on March 4, 1929, it was the plan to provide practically a continuous shed from Shields Creek to a point a few hundred feet east of the east end of Tunnel 11/2. At the time of the accident to Train No. 27 the only sheds we had in this vicinity were sheds Nos. 5 and 6 We generally have a number of slides when the weather softens up in February and March. The accident to train No. 27 occurred on March 4, 1929. Generally speaking, it is warm weather or rain which causes the slides -- depending, of course, on the amount of snow in the high hills.
