Abstract

One of the Pacific Northwest's most notable outdoor recreation areas, the "John Day Country" in northeastern Oregon, is named after a native Virginian who was a member of the Astor expedition to the mouth of the Columbia River in 1812. There is little factual information about John Day except that he was born in Culpeper County, Virginia, about 1770. It is known also that in 1810 this tall pioneer "with an elastic step as if he trod on springs" joined John Jacob Astor's overland expedition under Wilson Price Hunt to establish a vast fur-gathering network in the Western States based on a major trading post at the mouth of the Columbia River.

Volcanoes are mighty mountains

Volcanoes are evidence of the remarkable journey of molten rock, which begins miles (kilometers) beneath our feet. What happens on magma’s ascent determines whether it erupts explosively (like Mount St. Helens on May 18, 1980), oozes lava (like Mount St. Helens during its 2004–2008 dome-building event), or cools and crystallizes underground, never to erupt at all. This two-page educational activity uses a conceptual model of a stratovolcano to connect volcanic processes with personal growth. On page 1, students explore how magma is generated and moves through the crust to form a volcano, using core concepts we can relate to: strengths, support, challenges, motivations, and goals. On page 2, students reflect on their own journeys to draw parallels between what happens at volcanoes and how personal motivations and challenges shape them, just as magma shapes volcanoes, and volcanoes transform landscapes.

Key minerals in energy transmission

The electrical grid relies on minerals with unique properties to transform, transmit, and convert electricity. Transmission needs are growing—to support the expansion of data centers and link diverse energy resources into the grid. This expansion will require greater quantities of minerals. Although some minerals are produced in the United States, the United States relies on imports for others. This infographic shows the key minerals that support energy transmission, and how reliant the United States is on imports for these minerals.

3D Elevation Program—Hawaii

Using 3D Elevation Program data, a modern illustration of each State's landscape showcases its elevation differences in vivid detail. Each State has been consistently adjusted and colorized according to its highest and lowest elevations, accentuating differences even in States with low relief. To further emphasize landforms, shaded relief has been added on top of the elevation colors.
