Those hired in the 1970s and early 1980s brought diverse skillsets and new perspectives to the workforce. Like the earliest women rangers in the 1910s and 1920s, they often only had short-term positions. They all challenged ideas of what it takes to be a park ranger.

Mauna Loa and Kilauea in Hawaii Volcanoes National Park are shield volcanoes. diagram of a shield volcano with lava features Cinder Cones Cinder cones are typically simple volcanoes that consist of accumulations of ash and cinders around a vent. Sunset Crater Volcano and Capulin Volcano are cinder cones. photo of a dry grassy field with a cinder cone in the distance Series: Volcanic Features Volcanoes vary greatly in size and shape. Volcanoes also may have a variety of other features, which in turn, have a great range in diversity of form, size, shape, and permanence. Many volcanoes have craters at their summits and/or at the location of other vents. Some craters contain water lakes. Lakes of molten or solidified lava may exist on some volcanoes. Fumaroles and other geothermal features are a product of heat from magma reservoirs and volcanic gases. photo of a lava lake in a summit crater Series: Volcano Types Volcanoes vary in size from small cinder cones that stand only a few hundred feet tall to the most massive mountains on earth. photo of a volcanic mountain with snow and ice Series: Volcanic Eruption Styles Categories in this traditional classification are based on the eruption styles of particular volcanoes. These magmatic eruption styles are listed in the order of increasing explosivity. volcanic eruption with glowing lava Block Flows Block lava flows have surfaces that consist of large angular blocks of lava. photo of blocky lava flows in a mountain valley.

Updated Species Database Will Help Boost Amphibian Conservation Across the National Park System To steward amphibians effectively, managers need basic information about which species live in parks. But species lists need constant maintenance to remain accurate. Due to recent efforts, the National Park Service now has an up-to-date amphibian species checklist for almost 300 parks. This information can serve as the basis for innumerable conservation efforts across the nation. A toad sits on red sand, looking into the camera.

Lassen Volcanic Winter/Spring Guide National Park Service U.S. Department of the Interior Winter 2022 - 2023 Visitors enjoy the snow play area near the Kohm Yah-mah-nee Visitor Center in the Southwest Area. Welcome! Lassen Volcanic National Park receives as much as 30 feet of snow in its winter season. The resulting snowpack often lasts more than half of the year (approximately November to June). Despite the heavy snowfall, sunny skies are common between storms. These windows of "blue bird" days provide excellent opportunities to explore the park by snowshoe or ski or to simply enjoy the sights and sounds of winter. Southwest Area Manzanita Lake Area Steep slopes and sweeping vistas abound in the Southwest Area of the park. Beginning at 6,700 feet elevation, this area receives the most snow. The visitor center here is an excellent first stop for new winter explorers. See page 3 for location. The Manzanita Lake Area (5,800 elevation) consists of gentle slopes and scenic lakes. It offers the easiest routes for snowshoeing and cross-country skiing in the park. Vehicle Access The information desk and park store are available when the building is open. See hours on page 2. Light snacks and hot drinks may be available on weekends. The Manzanita Lake and Southwest Areas of the park are accessible throughout the winter season. Visitors can travel two miles from SR-44 to the Loomis Plaza in the Manzanita Lake Area and five miles north of SR-36 to the Kohm Yahmah-nee Visitor Center in the Southwest Area (See map on page 3). The park highway is closed to through traffic due to snow approximately November through May. During heavy winters, the highway may close to through traffic as early as late-October and open as late as mid-July. Other park roads to Juniper Lake, Butte Lake, and Warner Valley Areas are also closed in winter. Two routes around the park connect the Manzanita Lake and Southwest Areas. Travel time is approximately 90 minutes to 2 hours in normal winter driving conditions. Learn more on page 8.
