The story of Sealander park begins with Carl Sealander. Leaving Sweden in 1893 at the age of seventeen, Carl worked in mining communities across Colorado and Utah before meeting his wife, Lizzie Eklund, in Salt Lake City. She had immigrated from Finland. They were married in September 1901 and, with a team and wagon carrying their belongings, they traveled to the New Sweden area, West of Idaho Falls, as Homesteaders.
Lizzie and Carl had one son, Clause, who grew up exploring the lava beds and developed a deep love of the area. He enjoyed sharing the area he loved with friends and family and developed the park as a place for entertaining. After marrying his wife Edith, they held potluck dinners, song festivals, Easter egg hunts, picnics and parties. These occasions were made even more special by his accordian music. In the early days, donations were used for the park's upkeep and improvements. Today the park can be reserved for picnics, receptions, reunions, weddings, and corporate retreats. It is listed on the National Register of Historic Places and is a wonderful part of Idaho's history.
