Thunder Clouds Dwarf Teton Range – Wyoming
Grand Teton National Park which was established in 1929 by President Calvin Coolidge, is located in the Jackson Hole valley of Wyoming. It is connected with Yellowstone National Park to the North via the John D. Rockefeller, Jr. Memorial Parkway. The park owes much of existence to Rockefeller, who believed so strongly that the Jackson Valley needed to be preserved, that he purchased large portions of it, before turning control over to the Federal Government for conservation.
Summer weather in Grand Teton National Park is generally mild and pleasant, with warm days and cool nights. From June through August, daytime temperatures typically range from the mid-60s to the mid-80s°F (18–29°C), while nighttime temperatures can drop into the 30s and 40s°F (0–10°C). Afternoon thunderstorms are common, especially in July, bringing brief but intense rain, lightning, and occasional hail. The park’s high elevation means that even summer mornings can be chilly, so layering is recommended for outdoor activities. Despite occasional rain, summer is the best time for hiking, wildlife viewing, and enjoying the park’s breathtaking landscapes.
