In contrast, much of the Huckleberry Ridge tuff, which was erupted during a polarity transition or field excursion 1.92 m.y. ago and initially magnetized in an intermediate direction (</span><i>D</i><span>&nbsp;= 214.5°,&nbsp;</span><i>I</i><span>&nbsp;= −2.2°, and α</span><sub>95</sub><span>&nbsp;= 4.1°), has been partially remagnetized in a normal field. Much of the overprint of the Huckleberry Ridge tuff is carried in low‐temperature oxidation products with low coercivities and low blocking temperatures, so that it is commonly removed in peak alternating fields less than 200 Oe or at temperatures less than 400°C. Hematite, having higher coercivities and blocking temperatures, is partly responsible for remagnetization in some specimens, but neither alternating field nor thermal demagnetization enables recovery of the original thermal remanent magnetization in these samples. The chemical overprinting is most pronounced in the devitrified tuff of the flow interior. Stable magnetization is observed in the Huckleberry Ridge tuff in the less porous densely welded portions at the base and boundaries of partial cooling units and in the tuff of the distal margins, where groundwater influences were minimal. Paleomagnetic directions of chilled margins within compound cooling units of the Lava Creek and Huckleberry Ridge tuffs support geological evidence that eruption of each ash flow sheet was rapid and that the source calderas were formed during a short period of time.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/JB082i026p03677","usgsCitation":"Reynolds, R.L., 1977, Paleomagnetism of welded tuffs of the Yellowstone group: Journal of Geophysical Research, v. 82, no. 26, p. 3677-3693, https://doi.org/10.1029/JB082i026p03677.","productDescription":"17 p.","startPage":"3677","endPage":"3693","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":374170,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Idaho, Montana, Wyoming","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -113.466796875,\n              42.01665183556825\n            ],\n            [\n              -108.25927734375,\n              42.01665183556825\n            ],\n            [\n              -108.25927734375,\n              45.867062714815475\n            ],\n            [\n              -113.466796875,\n              45.867062714815475\n            ],\n            [\n              -113.466796875,\n              42.01665183556825\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","volume":"82","issue":"26","noUsgsAuthors":false,"publicationDate":"2012-09-20","publicationStatus":"PW","contributors":{"authors":[{"text":"Reynolds, Richard L. 0000-0002-4572-2942 rreynolds@usgs.gov","orcid":"https://orcid.org/0000-0002-4572-2942","contributorId":139068,"corporation":false,"usgs":true,"family":"Reynolds","given":"Richard","email":"rreynolds@usgs.gov","middleInitial":"L.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":787610,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Forty-nine taxa were identified from 5 stations representing stream orders 1 through 5. Aquatic insects comprised 88 percent of all taxa and 97 percent of all individuals from the Dietrich River. Diptera, especially Chironomidae, was the most abundant, followed by Plecoptera. Diamesinae was abundant at the headwaters, decreasing downstream; Orthocladiinae exhibited the reverse distribution pattern. Diversity of collections generally increased downstream. The station collections were compared using coefficients of similarity, cluster analysis, and taxonomy. Collections from adjacent stations were most similar and similarity decreased with increasing distance. The fauna was tentatively divided into zones with characteristic communities: a Diamesinae-Simuliidae fauna in zone I (stream order 1), zone II, a region of transition (orders 2-4), and an Orthocladiinae-Plecoptera-Ephemeroptera fauna in zone III (order 5).

Values increase from the structural axis of the basin toward the flanks. Close correlations between the water resistivities in the Madison and the Minnelusa indicate possible hydrologic connection between the two units. The low primary porosity from geophysical logs in the Madison indicates that secondary porosity is necessary to develop water supplies of economic importance from the Madison.

The pallid bat night is characterized by two roaming periods with an intervening period of night roosting.  Foraging pallid bats have a characteristic style of flight well suited to the taking of relatively large, substrate-roving or slow flying prey.  After the initial foraging period pallid bats locate one another through vocal communication and gather in night roosting clusters where they enter torpor.  Durations and scheduling of nocturnal activities vary seasonally.  Cool months are characterized by smaller colonies of bats, greater fidelity to certain colony sites, slower and later emergence, briefer foraging periods and longer periods of night roosting.  Up to 75 percent of the time spent away from diurnal retreats is devoted to night roosting in the autumn.  Young are born in June, and during most of the summer adult males do not seem to occur sympatrically with females and young.  Females and young appear to forage together in July and August, when little fidelity is shown to roosting sites, large colonies exist, emergence is faster and earlier, and more time is spent in foraging than in cooler months.  In mid-August a postbreeding dispersal occurs.  These activities and behaviors are discussed in terms of the energetic demands on the bats and the socialization of young.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Mammalogy","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Society of Mammalogists","publisherLocation":"Provo, UT","doi":"10.2307/1379326","usgsCitation":"O'Shea, T., and Vaughan, T.A., 1977, Nocturnal and seasonal activities of the pallid bat, Antrozous pallidus: Journal of Mammalogy, v. 58, no. 3, p. 269-284, https://doi.org/10.2307/1379326.","productDescription":"16 p.","startPage":"269","endPage":"284","numberOfPages":"16","costCenters":[],"links":[{"id":291857,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":291856,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2307/1379326"}],"volume":"58","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53e492cee4b0fff40428a5ca","contributors":{"authors":[{"text":"O'Shea, Thomas J. 0000-0002-0758-9730","orcid":"https://orcid.org/0000-0002-0758-9730","contributorId":78071,"corporation":false,"usgs":true,"family":"O'Shea","given":"Thomas J.","affiliations":[{"id":291,"text":"Fort Collins Science Center","active":true,"usgs":true}],"preferred":false,"id":497726,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Vaughan, Terry A.","contributorId":90648,"corporation":false,"usgs":true,"family":"Vaughan","given":"Terry","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":497727,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Many are cyclic, ranging from diurnal, seasonal, and annual cycles to climatic fluctuations of many hundreds or thousands of years.

The best data upon which to base predictions are those that directly measure a hydrologic phenomenon, such as stream discharge, lake level, and precipitation. Programs for collection of these data over a large area on a scientific basis, however, are less than 100 years old-not a very sound statistical base for predicting events that have recurrence intervals of at least that long.</p>\n</div>\n<p>&nbsp;</p>","language":"English","publisher":"American Geophysical Union","publisherLocation":"Washington, D.C.","doi":"10.1029/EO058i004p00188","usgsCitation":"Winter, T.C., and Wright, H., 1977, Paleohydrologic phenomena recorded by lake sediments: Earth and Space Science, v. 58, no. 4, p. 188-196, https://doi.org/10.1029/EO058i004p00188.","productDescription":"9 p.","startPage":"188","endPage":"196","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":392,"text":"Minnesota Water Science Center","active":true,"usgs":true}],"links":[{"id":326391,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"58","issue":"4","noUsgsAuthors":false,"publicationDate":"2011-06-03","publicationStatus":"PW","scienceBaseUri":"57ada1e7e4b0f412a62dfab4","contributors":{"authors":[{"text":"Winter, Thomas C.","contributorId":84736,"corporation":false,"usgs":true,"family":"Winter","given":"Thomas","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":645228,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wright, H.E.

A least-squares shaping and predictive error filter approach was used. The relations were ranked in part according to the root mean square (r.m.s.) error of fit across the entire sample space. The tilt data with an annual range of tilt of approximately 10 microradians were fitted to the combined weather data of temperature and rainfall with a 0.75-microradian r.m.s. error. The best fit of earthquakes to these same tilt data is the subclass of events with magnitude (M) &gt; 2.5 within 30 kilometers of the tilt site. The filter that mapped earthquakes to tilt yielded a 1.03-microradian r.m.s. error. The most unusual tilt anomaly over the entire 2-year period has the best fit of rainfall to the data for any single month of the entire data set. This unusual anomaly was the basis of an erroneously predicted earthquake (M ∼ 5). These data indicate that if there are premonitory earthquake signals, they are buried in local meteorlogical noise. Separating an earthquake anomaly from the response to surface phenomena becomes more difficult as the earthquake anomaly lead time approaches the rise time of the soil to weather and seasonal variations.</span></span></p>","language":"English","publisher":"American Association for the Advancement of Science","doi":"10.1126/science.197.4299.154","issn":"00368075","usgsCitation":"Wood, M., and King, N., 1977, Relation between earthquakes, weather, and soil tilt: Science, v. 197, no. 4299, p. 154-156, https://doi.org/10.1126/science.197.4299.154.","productDescription":"3 p.","startPage":"154","endPage":"156","costCenters":[],"links":[{"id":219184,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"197","issue":"4299","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"50e4a637e4b0e8fec6cdc11f","contributors":{"authors":[{"text":"Wood, M.D.","contributorId":63930,"corporation":false,"usgs":true,"family":"Wood","given":"M.D.","email":"","affiliations":[],"preferred":false,"id":357068,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"King, N.E.","contributorId":29950,"corporation":false,"usgs":true,"family":"King","given":"N.E.","email":"","affiliations":[],"preferred":false,"id":357067,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
