US-4814933 Northern Lights in Alaska

Northern Lights (aurora borealis) are caused by a reaction of ionized particles in the atmosphere near the Earth’s poles and are typically visible in northern latitudes from late autumn to early spring.

In Alaska it is even possible to see Northern Lights in  Anchorage but the Lights would be a bit lower on the horizon and light pollution makes it a lot more difficult. 

A great location is Nancy Lake State Recreation Area and locals do say that the views from Flattop Overlook are spectacular.  Another recommended spot is the Glenn Alps. Fairbanks, Nome as well as Denali National Park are also said to be other good locations.

This postcard shows the Northern Lights in Alaska over Portage Lake and Chugach Mountains.  This postcard came from Ruth (22 August 2017).

US-3598927 DE-4546752 US-5370783 Denali (Mount McKinley) highest mountain peak in North America

Denali (also known as Mount McKinley) is the highest mountain peak in North America, with a summit elevation of 20,310 feet (6,190.5 m) above sea level. It is located in the Alaska Range in the interior of the U.S. state of Alaska. Denali is the centrepiece of Denali National Park and Preserve.

The Koyukon people who inhabit the area around the mountain have referred to the peak as "Denali" for centuries. In 1896, a gold prospector named it "Mount McKinley" in support of then-presidential candidate William McKinley; that name was the official name recognized by the United States government from 1917–2015. In August 2015, following the 1975 lead of the state of Alaska, the U.S. Department of the Interior announced the change of the official name of the mountain to Denali.

Denali has two significant summits: the South Summit is the higher one, while the North Summit has an elevation of 19,470 ft (5,934 m). The North Summit is sometimes counted as a separate peak.

Five large glaciers flow off the slopes of the mountain. The Peters Glacier lies on the northwest side of the massif, while the Muldrow Glacier falls from its northeast slopes. Just to the east of the Muldrow, and abutting the eastern side of the massif, is the Traleika Glacier. The Ruth Glacier lies to the southeast of the mountain, and the Kahiltna Glacier leads up to the southwest side of the mountain. With a length of 44 mi (71 km), the Kahiltna Glacier is the longest glacier in the Alaska Range. Source: Wikipedia

Personal Note:

We saw Denali while travelling on Alaska Rail to Talkeetna.  But in the next few days when we were staying in Talkeetna Alaskan Lodge, we could not see the mountain as it was hidden by its own clouds.

These two postcards came from Mindy P. (US-3598927) and Frank (DE-4546752) both Postcrossing.  I received a similar postcard to US-3598927 from Mike of Athens, GA (US-5370783, 3 July 2018) but this copy was badly eaten by the snails in my letterbox.
