Fishing Boating General fshing season opens May 29 and closes November 7, 2021. Some areas remain closed until June 15. Fishing permits are required in Yellowstone; state-issued fshing permits are not valid within the park. Anglers 16 years or older need a permit; younger children can fsh for free with a permitted adult. You can purchase a fshing permit in the park, in local gateway communities, or online via www.recreation.gov. Fishing regulations in Yellowstone protect the unique values of the park ecosystem and conserve native fsh species. Copies of the complete park regulations are available wherever permits are sold and online at go.nps.gov/fsh. Possession limits and closures vary. Anglers are responsible for knowing the regulations in the area they are fshing and knowing how to tell the diference between species. Native fsh must be released unharmed back into the water immediately. These include: • Arctic grayling • Cutthroat trout • Mountain whitefsh Riding the Yellowstone River Trail. Horses, Mules, and Other Stock Animals These tackle and gear restrictions apply: • Hooks must be barbless. • Tackle and lures must be non-toxic. Lead tackle is not allowed. • Bait is prohibited. • Felt-soled footwear is not permitted. Traveling in the Yellowstone backcountry with horses, mules, or llamas is an exciting way to see the park. By their very nature, these large animals have the potential to leave great impacts on the land. Permits are required for both day rides and overnight trips. To get a permit and plan a safe, enjoyable, low-impact trip, contact a backcountry ofce or look online at go.nps.gov/YELLhorseride. • Trails typically open for stock use July 1. Some trails may open earlier or later depending on trail conditions. • Proof of a negative Coggins test is required. • Hay is prohibited in the backcountry, and weedfree hay restrictions are enforced in other areas. • Stock may not be left at trailheads or kept in front-country, drive-in campgrounds overnight.

All watercraft (motorized boats, non-motorized boats, and foat tubes) must have a permit and be inspected for aquatic invasive species by park staff. Any watercraft suspected of harboring AIS will be subject to a non-chemical decontamination treatment. Aquatic Invasive Species are nonnative plants and animals that can cause irreversible harm to the ecosystem. New Zealand mudsnails, whirling disease, and lake trout have already resulted in loss of native fsh or closure of some park areas. Watercraft users and anglers are asked to inspect all items that may come in contact with park waters, ensuring that they are clean, drained, and dry. Motorized boating is allowed on Lewis Lake and most of Yellowstone Lake. Only non-motorized boating is allowed on most other lakes. Only one river is open to non-motorized boating: the Lewis River channel between Lewis and Shoshone lakes.

You may have to wait a while, so be ready. Know Your Camera's Limits A cell phone camera will not be able to capture the same resolution and detail as a more advanced standalone camera with large lenses. Good photography isn't about getting close to the animal for a close-up. It's about having the right equipment for the job. 6 Yellowstone Visitor Guide • BE ALERT FOR BEARS. • MAKE NOISE in areas with limited visibility. • CARRY BEAR SPRAY, one can with each adult, and know how to use it. • HIKE IN GROUPS of three or more people. • DO NOT RUN; back away slowly.

Summer 2021 7 Famously Hot Features Yellowstone was established in 1872 as the world's frst national park primarily because of its unparalleled collection of geysers, hot springs, mudpots, and steam vents. * ...--.- Stay on Boardwalks and designated trails. Do not touch any thermal features, and keep foreign objects out of springs. It can be windy, so cinch your hats, and secure your items. Unstable ground and boiling waters make hydrothermal areas extremely dangerous. Fumaroles, or steam vents, are the hottest hydrothermal features in the park, with temperatures well above that of boiling water. They are easier to see in cool weather. Geysers erupt with steaming hot water. Variations in each geyser's underground reservoir determine whether it is regular and predictable—like Great Fountain Geyser in the Lower Geyser Basin—or irregular like Giant Geyser in the Upper Geyser Basin. Hot springs are the most common hydrothermal features in the park. They vary from frothing mochalike boiling water to clear and calm pools of tremendous depth. Mudpots are acidic features with a limited water supply. Their consistency and activity vary with the seasons and precipitation. Travertine terraces are found at Mammoth Hot Springs, where the interactions of hot water and limestone deep underground create chalk-white travertine terraces at the surface. Norris Geyser Basin.

Although wolves once roamed from the Arctic tundra to Mexico, loss of habitat and extermination programs led to their demise throughout most of the United States by the early 1900s. In 1973, the US Fish and Wildlife Service listed the gray wolf (Canis lupus) as an endangered species and designated the Greater Yellowstone Ecosystem as one of three re
