The Grand Canyon of the Yellowstone is the first large canyon on the Yellowstone River downstream from Yellowstone Falls in Yellowstone National Park.
The canyon is approximately long, between deep and from wide. 
Yellowstone National Park contains at least 45 named waterfalls and cascades, and hundreds more unnamed, even undiscovered waterfalls over high.
The highest plunge type waterfall in the park is the lower Falls of Yellowstone Falls at .
The highest horsetail type is Silver Cord Cascade at . 
Grand Teton National Park has a semi-arid climate with the wettest months between November and January, mostly in the form of snow.
The park averages of snow in the mountains and in the valley annually.
In January, the daily temperature range averages between during the day to at night.
During the month of July, the daily temperature range is and .
The record high is and the record low is .
Temperatures above the valley in the mountains during the summer average 1 degree cooler for every of altitude gained, so high altitude passes may remain snow covered until mid-July.
Thunderstorms are common during the summer, especially over the mountains; by contrast, no tornados have ever been reported within the park.
The F4 Teton-Yellowstone tornado was a high altitude tornado which touched down northeast of the park on the border of the Teton Wilderness of Bridger-Teton National Forest and Yellowstone National Park. 
Eagle Peak is a mountain in the Absaroka Range in the U.S. state of Wyoming and at is the highest point in Yellowstone National Park.
It is located about east of the southeast arm of Yellowstone Lake. 
Yellowstone climate is greatly influenced by altitude, with lower elevations generally found to be warmer year round.
The record high temperature was in 2002, while the coldest temperature recorded is in 1933.
During the summer months of June through early September, daytime highs are normally in the range, while nighttime lows can go to below freezing (0 °C)—especially at higher altitudes.
Summer afternoons are frequently accompanied by thunderstorms.
Spring and fall temperatures range between with cold nights in the teens to single digits (−5 to −20 °C).
Winter in Yellowstone is very cold with high temperatures usually between zero to 20 °F (−20 to −5 °C) and nighttime temperatures below zero °F (−20 °C) for most of the winter.
Precipitation in Yellowstone is highly variable and ranges from annually near Mammoth Hot Springs, to in the southwestern sections of the park.
The precipitation of Yellowstone is greatly influenced by the moisture channel formed by the Snake River Plain to the west that was, in turn, formed by Yellowstone itself.
Snow is possible in any month of the year, with averages of annually around Yellowstone Lake, to twice that amount at higher elevations.
Tornadoes in Yellowstone are rare; however, on July 21, 1987, the most powerful tornado recorded in Wyoming touched down in the Teton Wilderness of Bridger-Teton National Forest and hit Yellowstone National Park.
Called the Teton–Yellowstone tornado, it was classified as an F4, with wind speeds estimated at between .
The tornado left a path of destruction wide, and long, and leveled of mature pine forest.
Both high elevation areas are classified as humid continental (Dfb), according to Köppen-Geiger climate classification.
