Everything about Mount Dana totally explained
Mount Dana is a
mountain on the eastern edge of
Yosemite National Park in the
U.S. state of
California. At an elevation of, it's the second highest mountain in Yosemite (after
Mount Lyell). Mount Dana is the highest peak in Yosemite that's a simple hike to the summit. Mount Dana is named after
James Dwight Dana, who was a professor of
geology at
Yale College
Mount Dana is composed of
prebatholithic rock that's mostly reddish
metamorphic rock, which was composed by metavolcanics of surfacing magma from the
Mesozoic Era.
Mount Dana's northern face includes a small, receding glacier known as the
Dana Glacier.
The
Dana Meadows lie at the foot of the mountain.
From the top, lakes throughout Dana Meadows,
Mono Lake, and many other mountains are in view.
The Hike
Mount Dana is typically hiked from its western face beginning at the
Tioga Pass Yosemite Park entrance and
is a
class 1-2 hike, rising in elevation in from the park entrance at
Tioga Pass (a 20.3% average grade). The trail isn't maintained, so users must assume any risk.
There is a clearly marked path leading just above
tree line. After topping a ridge, a set of
use-paths and
ducked routes are present, with the main path running along the easterly ridgeline. Additionally, numerous alternate trail segments begin and end at various points on the southwestern face, making parts of this hike a difficult class 2. The path segments turn into
scree toward the summit, where a shallow stone-walled shelter and register are found. Significant snow fields on the mountain slopes can exist late into the summer season. Total round trip hiking time can be anywhere between 3 and 12 hours depending many factors, such as acclimatization to elevation.
After reaching a plateau above the tree line, almost all vegetation disappears with the exception of
lichen and a few high alpine
Sky Pilot (
Polemonium eximium).
Fauna are largely limited to spiders and insects, such as black/brown
grasshoppers. The only
mammals other than humans are
marmots, often fed by hikers against Park warnings.
Thunderstorms are known to arise suddenly, making the rocks slippery, and the hiking dangerous year round. Temperatures can drop very quickly, with hot 100 °F (38 °C) weather dropping to freezing levels during a
hailstorm.
Even experienced hikers can face
altitude sickness, due to the
high elevation.
