By Mark Floyd Correspondent PHOTO BY JERRY BALDOCK Trey Stadeli breaks a Burns tackle for a long gain after a reception. Outlaws /efeate/ on football opener By Rongi Yost Correspondent The Outlaws were defeated 33-7 by Burns at home in Sisters on Friday, August 31. Burns marched down the field and scored the first touchdown of the contest. Their PAT was good and the Hilanders took a 7-0 lead. Sisters got on the score- board in the second quar- ter. Taylor Fendall threw a 25-yard pass to Trey Stadeli down to the five-yard line, and followed with a slant to Korbin Sharp for the touch- down. Wyatt Hernandez made a tremendous kick that flew through the middle of the uprights for the PAT, a shot that could have made it from 50 yards out. The Hilanders also had a TD in the second quarter and at the half were on top 14-7. They added 19 points in the second half and posted the win. Burns boasted some very big linemen, one at 280 pounds, and a bunch at 220 and 230 pounds, which they used to their advantage. Fendall said, “They pounded us up front, and ran it down our throat in the first, third, and fourth quarters.” Matt Harris led the Outlaws with six-and-a-half tackles. Ben Johnson had a very good defensive game, including two pass deflec- tions and five tackles. He also corralled the ball for a spec- tacular 30-yard catch under very tight coverage. Seniors Matt Harris and Korbin Sharp shared their thoughts on the game. “We got in some big hits and had good effort from everyone tonight,” said Harris. Sharp said, “It sucks that we lost, but we all kept our heads up and fought to the end.” Coach Fendall said, “We have to just keep fight- ing because improvement’s all we got from that. Burns kicked our butt and that’s about it. We are young and our kids hung in there. We just have to keep them from unraveling during the game, and keep forging ahead. The Outlaws will travel to Valley Catholic on Friday, September 7. CORVALLIS – Some of the clearest, most compre- hensive images of the top several miles of the Earth’s crust have helped scientists solve the mystery of why Mount St. Helens is located outside the main line of the Cascade Arc of volcanoes. A giant subsurface rock formation some 20-30 miles in diameter, known as the Spirit Lake batholith, appears to have diverted magma and partially melted rock outside of the arc and to the west, forming the region’s most active volcano. Results of the study, which was supported by the National Science Foundation and carried out in collabora- tion with the U.S. Geological Survey, are being pub- lished this week in Nature Geoscience. Previous imaging studies have primarily utilized seis- mic methods. During natural earthquakes and artificially induced tremors – by setting off explosions – scientists can image some of the prop- erties of subsurface rocks by tracking the sound waves. This method provides clues to the structure, density and temperature of the rocks. More recently, researchers are using “magnetotelluric,” or MT data, which measures the Earth’s subsurface elec- trical conductivity. Variations in the geomagnetic and geoelectric fields can reveal much about the subsurface structure and temperature, as well as the presence of fluids such as magma. “Either method by itself can lead to a level of uncer- tainty, but when you layer them together as we have done in this project you get a much clearer picture of what lies below,” said Adam Schultz, an Oregon State University geophysicist who is principal investigator on the NSF grant to OSU and co-author on the Nature Geosciences paper. “The longer you run the measurements, the crisper the images and the deeper you can ‘see’ the subsurface. We were focusing on the upper 12-15 kilometers of the crust, but with a longer experiment we could see 200 to 300 kilometers below the surface.” Understanding the for- mation of Mount St. Helens begins with plate tectonics. Similar to the present day, where the Juan de Fuca plate is being subducted beneath North America, in the past crustal blocks with marine sediments were “slammed into the continent, where they accreted,” Schultz said. “This material is more permeable than surrounding rock and allows the magma to move through it,” he noted. “The big batholith acts kind of like a plug in the crust and diverted magma that nor- mally would have erupted Organic, natural products Personal approach for every lawn 22 years in business • LCB#9583 541-549-2882 Summer cleanups Mowing & pruning Irrigation repair & start-ups People- & Pet-Friendly Lawn Maintenance Services in line with the other major Cascade volcanoes, result- ing in St. Helens forming to the west of the Cascadia Arc, and Mt. Adams slightly to the east.” Mount St. Helens expe- rienced a major eruption in May of 1980 and since has gone through periods of dome-building (2004-08) and dormancy. A study in 2006 by researchers from the University of Canterbury in New Zealand provided some images of the volcano’s sub- surface. During the next year, Schultz and the author of the 2006 study will use magneto- telluric technology to gather new and hopefully crisper images to see how much has changed since that study. Schultz said that the images from the latest study are clear enough that by continuously monitoring the geoelectric and geomagnetic fields, they may be able to detect changes in the move- ment of magma beneath Mount St. Helens, and per- haps other volcanoes. “This may give us a new tool to monitor the magma cycle so we don’t have to wait for the dome-building phase to tell us conditions are changing,” Schultz said. Schultz is in OSU’s College of Earth, Ocean, and Atmospheric Sciences. Have a story idea for The Nugget? We’d love to hear it! Send an email to editor@nuggetnews.com GET FOLKED UP!
