Getting there and getting around on the John Muir Trail

The best time to hike the John Muir Trail (JMT) is late summer. To plan your own adventure, start by reading up on the trek at various websites such as the Pacific Crest Trail Association’s JMT trail site (www.pcta.org/discover-the-trail/john-muir-trail/) and in guidebooks. Then, when you know when you want to go, procure your permits. To start in Yosemite, you can apply for permits through their lottery over the winter or get a permit for an alternate trailhead like we did.

Hazards abroad: Sent home

On May 19, 2012, seismologist Roger Bilham of the University of Colorado at Boulder landed at the airport in Delhi, India, on his way to Bhutan. He debarked from the plane and was met by Indian customs officials, who declared he was on the “blacklist” and not allowed entry to India, despite having a valid visa. Two hours later, he was on a plane heading back to the U.S.

Rescuing data from the dark

Along with the proliferation of techniques and technologies to deal with Big Data — the large volumes of data coming in from global sensors and satellites that can require supercomputers to crunch — geoscientists are also addressing the collection and integration of what could be termed small (or mainstream) data.

Spotlight on UCORE projects

The National Science Foundation-funded Undergraduate Catalytic Outreach and Research Experience (UCORE) program ran from 2007 to 2012 and involved 132 students from six different community colleges in Oregon. During the five years of the UCORE program, groups of three to six community college students from each campus spent 10 weeks in the summer on the University of Oregon campus, working on projects alongside graduate students and faculty in chemistry, geological sciences and physics research groups. Listed below are some of the projects in which the students were involved.

Disaster debris hotlines and fast grants

Two years after the March 2011 earthquake and tsunami that devastated Japan, debris set adrift by the destructive waves continues to wash up on beaches along the west coast of the United States and Canada.

Beachcombers can report tsunami-related or hazardous debris by emailing DisasterDebris@noaa.gov or calling 1-855-WACOAST in Washington or 211 in Oregon. As of Dec. 13, NOAA had received 1,432 reports of debris, 17 of which were confirmed as tsunami-related.

Florida swamps - ancient sinkholes

In Florida, the limestone bedrock is protected by a surface layer of sand and clay. Thus, when a sinkhole forms naturally, over centuries, sand and clay fill the void, creating a muddy depression. These depressions tend to evolve into swamps.

The first dinner in a beast

Surprisingly, there is precedence for eating dinner in the body of a massive beast. In February 1802, Rembrandt Peale, an early American painter best known for his portraits of George Washington and Thomas Jefferson, invited 12 friends and family to dine under the rib cage of a mammoth, which had recently been erected in his father’s museum in Philadelphia.

Gain some, lose some

Scientists now know that Earth’s rotation is very slowly decelerating, such that the length of the rotational day is about two milliseconds longer than the 86,400 seconds it was nearly two centuries ago. But that doesn’t mean Earth’s rotation is always slowing down. The tidal force of the moon acts to slow Earth’s rotation by taking away some of the planet’s energy. But other factors, such as the expansion and contraction of the atmosphere with the seasons, the churning of material within Earth’s core, and the rebounding of Earth’s surface as the weight of glaciers is removed, can sometimes act to speed up Earth’s rotation by redistributing its mass, thereby altering Earth’s moment of inertia and thus its speed of rotation.
