Though it might pale in comparison to Mount Shasta's grandeur, Black Butte is still a prominent landmark in southern Siskiyou County and it definitely captivates drivers with its conical shape as they approach it on Interstate 5. Hiking it to the top will allow you to get acquainted with its particular surface formed from viscous lava and it will also unveil the well-kept secret of its lush northern valley.

The end of the Crags Trail is marked by a sign on a tree, but you probably won't notice because you will be too busy marveling at the granite spires and views of Mt Shasta. Take time to explore the top as there is much to see here but watch for steep dropoffs.

In the fall you can literally hike up to the summit of this tallest free-standing mountain in the lower US via the eastern route without climbing or any snow. The standard Avalanche Gulch route would be too dangerous without snow due to frequent life-threatening rockfall.

Impressive waterfall deep below the Falls Trail which leads along the rim. A deep pool invites for swimming below the waterfall, while very high cliffs on the western side are used by some fearless cliff jumpers.

Ice-skating in hot summer deep underground in a volcanic lava cave? Yes, while it is over 100Β°F outside, some caves here preserve cold winter temperatures long into the summer, some throughout the year. This cave with a steep descent deep into a 7000 year-young lava tube cave, reaching down three levels, with large icicles and and underground frozen lake on the lowest level. The cave was formed by volcanic gas bubbling through liquid lava dunging the last eruption of a Modoc cascade volcano, and connects underground to the western side of Medicine Lake Road (highway 49). Warning: None of the many caves here have any signage or guidance, many are long with multiple confusing branches, narrow crawl/climbing sections, sudden deep drops, loose rock, water and ice underground. Only teams of experienced cavers with the right equipment should attempt exploration.

Mount Shasta (Karuk: Γytaahkoo or "White Mountain") is a potentially active volcano located at the southern end of the Cascade Range in Siskiyou County, California. At an elevation of 14,179 feet (4321.8 m), it is the second highest peak in the Cascades and the fifth highest in California. Mount Shasta has an estimated volume of 85 cubic miles (350 km3), which makes it the most voluminous stratovolcano in the Cascade Volcanic Arc. Shasta dominates the northern California landscape. It rises abruptly and stands nearly 10,000 ft (3,000 m) above the surrounding terrain. On a clear winter day, snowy Mount Shasta can be seen from the floor of the Central Valley 140 miles (230 km) to the south. The mountain consists of four overlapping volcanic cones that have built a complex shape, including the main summit and the prominent satellite cone of 12,330 ft (3,760 m) Shastina, which has a visibly conical form. If Shastina were a separate mountain, it would rank as the fourth-highest peak of the Cascade Range (after Mount Rainier, Rainier's Liberty Cap, and Mount Shasta itself). Mount Shasta's surface is relatively free of deep glacial erosion except, paradoxically, for its south side where Sargents Ridge runs parallel to the U-shaped Avalanche Gulch. This is the largest glacial valley on the volcano, although it does not presently have a glacier in it. There are seven named glaciers on Mount Shasta, with the four largest (Whitney, Bolam, Hotlum, and Wintun) radiating down from high on the main summit cone to below 10,000 ft (3,000 m) primarily on the north and east sides. The Whitney Glacier is the longest, and the Hotlum is the most voluminous glacier in the state of California. Three of the smaller named glaciers occupy cirques near and above 11,000 ft (3,400 m) on the south and southeast sides, including the Watkins, Konwakiton, and Mud Creek glaciers. https://en.wikipedia.org/wiki/Mount_Shasta
