December 26 is an important date in Idaho's history. Here are five interesting facts about this day:

1. The famous explorer John C. Fremont arrived in the Boise River Valley on December 26, 1843. He and his party were the first non-Native Americans to explore the area, and Fremont dubbed the Boise River "Riviere Aux Bois" because of the dense forests that surrounded it.

2. On December 26, 1869, the territorial legislature of Idaho voted to move the capital from Lewiston to Boise. The move was made official the following year, and the city has been the capital of Idaho ever since.

3. A devastating earthquake struck southern Idaho on December 26, 1934. The quake, which had a magnitude of 6.6, caused extensive damage in the towns of Challis and Mackay. It also triggered several landslides and caused the collapse of several buildings.

4. On December 26, 1971, the Sun Valley ski resort hosted its first ever World Cup ski race. The event was a huge success, and Sun Valley went on to host many more World Cup races over the years.

5. In 2015, Idaho Governor Butch Otter issued an executive order on December 26 declaring it "Basaing Day" in honor of the state's Basque community. The Basques are an ethnic group from the Pyrenees region of Europe who have a strong cultural presence in Idaho, particularly in the town of Boise. Basque immigrants began arriving in Idaho in the late 19th century to work in the state's mining and sheep-herding industries, and their descendants continue to play an important role in the state's cultural and economic life.
