The US purchased Alaska from Russia in 1867 so there is still some Russian influence here. We have run across several fully functional Russian Orthodox churches during our travels here. We visited a few of them today that are near Anchorage.
The graveyard near the two St. Nicholas Churches is an Orthodox Christian Cemetery, and is still in use today. Spirit Houses are placed over the grave 40 days after the burial to house the spirit of the deceased and their possessions. The colors of the houses are specific to the families. This is sort of a combination of Russian and native burial practices.
