The seven facies association include a mixed sequence of intracaldera ash-flow tuffs and breccias, alluvial and lake margin deposits, and tuffaceous lake beds. These deposits represent volcanic units related to caldera collapse and emplacement of the Snowshoe Mountain Tuff, and sediments and pyroclastic material deposited in the newly formed caldera basin, Early sedimentation is interpreted to have been rapid, and to have occurred in volcaniclastic fan environments at CCM-1 and in a variery of volcaniclastic fan, braided stream shallow lacustrine, and mudflat environments at CCM-2. After an initial period of lake-level rise, suspension settling, turbidite, and debris-flow sedimentation occurred in lacustrine slope and basin environments below wave base. Carbonate sedimentation was initially sporadic, but more continuous in the latter part of the recorded lake history (after the H fallout tuff). Sublacustrine-fan deposition occurred at CCM-1 after a pronounced lake-level fall and subsequent rise that preceded the H tuff. Variations in density, neutron, gamma-ray, sonic, and electrical properties of deposits penetrated oin the two holes reflect variations in lithology, porosity, and alteration. Trends in the geophysical properties of the lacustrine strata are linked to downhole changes in authigenic mineralology and a decrease in porosity interpreted to have resulted primarily from diagenesis. Lithological and geophysical characteristics provide a basis for correlation of the cores; however, mineralogical methods of correlation are hampered by the degree of diagenesis and alteration.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"GSA Special Papers","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Geological Society of America","doi":"10.1130/0-8137-2346-9.159","usgsCitation":"Larsen, D., and Nelson, P.H., 2000, Stratigraphy, correlation, depositional setting, and geophysical characteristics of the Oligocene Snowshoe Mountain Tuff and Creede Formation in two cored boreholes: GSA Special Papers, v. 346, p. 159-178, https://doi.org/10.1130/0-8137-2346-9.159.","productDescription":"20 p.","startPage":"159","endPage":"178","numberOfPages":"20","costCenters":[],"links":[{"id":281497,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281495,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/0-8137-2346-9.159"}],"country":"United States","state":"Colorado","otherGeospatial":"Creede Formation;Oligocene Snowshoe Mountain Tuff","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -108.8051,37.0476 ], [ -108.8051,37.9054 ], [ -106.6216,37.9054 ], [ -106.6216,37.0476 ], [ -108.8051,37.0476 ] ] ] } } ] }","volume":"346","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd7477e4b0b29085109905","contributors":{"authors":[{"text":"Larsen, Daniel","contributorId":27495,"corporation":false,"usgs":true,"family":"Larsen","given":"Daniel","affiliations":[],"preferred":false,"id":489249,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Nelson, Philip H. pnelson@usgs.gov","contributorId":862,"corporation":false,"usgs":true,"family":"Nelson","given":"Philip","email":"pnelson@usgs.gov","middleInitial":"H.","affiliations":[{"id":164,"text":"Central Energy Resources Science Center","active":true,"usgs":true}],"preferred":true,"id":489248,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Specific conductance, alkalinity, chloride, dissolved organic carbon, boron, sodium, strontium, and deuterium in ground water are considered to be indicators of the leachate plume at this site.\n\nLeaf samples of broad-leafed cottonwood, Populus deltoides, were collected from 57 sites around the closed landfill. Cottonwood, a phreatophyte or “well plant,” functions as a & surrogate well and serves as a ground water quality sampler. The leaf samples were combusted to ash and analyzed by instrumental neutron activation for 35 elements and by prompt-gamma instrumental neutron activation, for boron. A monitoring well was located within a few meters of a sampled cottonwood tree at 15 of the 57 sites, and ground water samples were collected from these monitoring wells simultaneously with a leaf sample. The chemical analyses of the ground water and leaf samples from these 15 sites indicated that boron, bromine, sodium, and strontium concentrations in leaves were significantly correlated with leachate indicator constituents in ground water. A point-plot map of selected percentiles indicated high concentrations of boron, bromine, and sodium in leaf ash from sites downgradient of the most recent landfill and from older landfills nearby.\n\nData from leaf analysis greatly extended the known areal extent of the leachate plume previously determined from a network of monitoring wells and geophysical surveys. This phytosgeochemical study provided a cost-effective method for assessing the extent of a leachate plume from an old landfill. Such a method may be useful as a preliminary sampling tool to guide the design of hydrogeochemical and geophysical studies.","language":"English","publisher":"Wiley","doi":"10.1111/j.1745-6592.2000.tb00258.x","usgsCitation":"Erdman, J.A., and Christenson, S., 2000, Elements in cottonwood trees as an indicator of ground water contaminated by landfill leachate: Groundwater Monitoring & Remediation, v. 20, no. 1, p. 120-126, https://doi.org/10.1111/j.1745-6592.2000.tb00258.x.","productDescription":"7 p.","startPage":"120","endPage":"126","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":282828,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282827,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1111/j.1745-6592.2000.tb00258.x"}],"country":"United States","state":"Oklahoma","city":"Norman","otherGeospatial":"Norman Landfill Research Site","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -97.547822,35.145318 ], [ -97.547822,35.348324 ], [ -97.176918,35.348324 ], [ -97.176918,35.145318 ], [ -97.547822,35.145318 ] ] ] } } ] }","volume":"20","issue":"1","noUsgsAuthors":false,"publicationDate":"2007-02-22","publicationStatus":"PW","scienceBaseUri":"53cd5757e4b0b290850f76bc","contributors":{"authors":[{"text":"Erdman, James A.","contributorId":37748,"corporation":false,"usgs":true,"family":"Erdman","given":"James","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":491027,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Christenson, Scott","contributorId":59128,"corporation":false,"usgs":true,"family":"Christenson","given":"Scott","affiliations":[],"preferred":false,"id":491028,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The Going-to-the-Sun Road is the only road that crosses Glacier National Park, Montana. This 80-km highway ascends over 1200m along the wall of a glaciated basin and crosses the continental divide. The annual opening of the road is critical to the regional economy and there is public pressure to open the road as early as possible. Despite the 67-year history of snow removal activities, few stat on snow conditions at upper elevations were available to guide annual planning for the raod opening. We examined statistical relationships between the opening date and nearby SNOTEL data on snow water equivalence (WE) for 30 years. Early spring SWE (first Monday in April) accounted for only 33% of the variance in road opening dates. Because avalanche spotters, used to warn heavy equipment operators of danger, are ineffective during spring storms or low-visibility conditions, we incorporated the percentage of days with precipitation during plowing as a proxy for visibility. This improved the model's predictive power to 69%/ A mountain snow simulator (MTSNOW) was used to calculate the depth and density of snow at various points along the road and field data were collected for comparison. MTSNOW underestimated the observed snow conditions, in part because it does not yet account for wind redistribution of snow. The severe topography of the upper reaches of the road are subjected to extensive wind redistribution of snow as evidence by the formation of \"The Big Drift\" on the lee side of Logan Pass.","largerWorkTitle":"Proceedings of the 2000 International Snow Science Workshop","conferenceTitle":"A merging of theory & practice: ISSW 2000","conferenceDate":"2000-10-01T00:00:00","conferenceLocation":"Big Sky, MT","language":"English","publisher":"International Snow Science Workshop","publisherLocation":"Bozeman, MT","usgsCitation":"Fagre, D.B., and Klasner, F.L., 2000, Application of snow models to snow removal operations on the Going-to-the-Sun Road, Glacier National Park, p. 266-272.","productDescription":"p. 266-272","numberOfPages":"7","costCenters":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"links":[{"id":281244,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Montana","otherGeospatial":"Glacier National Park","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -114.4755,48.2337 ], [ -114.4755,49.001 ], [ -113.242,49.001 ], [ -113.242,48.2337 ], [ -114.4755,48.2337 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd4d9ee4b0b290850f19a3","contributors":{"authors":[{"text":"Fagre, Daniel B. 0000-0001-8552-9461 dan_fagre@usgs.gov","orcid":"https://orcid.org/0000-0001-8552-9461","contributorId":2036,"corporation":false,"usgs":true,"family":"Fagre","given":"Daniel","email":"dan_fagre@usgs.gov","middleInitial":"B.","affiliations":[{"id":481,"text":"Northern Rocky Mountain Science Center","active":true,"usgs":true}],"preferred":true,"id":488815,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Klasner, Frederick L.","contributorId":51373,"corporation":false,"usgs":true,"family":"Klasner","given":"Frederick","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":488816,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
