Baldwin hallForest Park Museum and Arboretum was originally developed in the 1940's by Eugene Hastie, a farmer, local historian and author. The arboretum was planted in straight lines to allow farming between the rows of growing trees.

Since the original purchase of the 5-acre park in 1966, the Dallas County Conservation Board has added 12 acres of re-established prairie and wildflowers and a paved spur of the Raccoon River Valley Trail,  RRVT map  There is also a mowed walking trail that perimeters the prairie. The arboretum consists of over 100 different species of primarily native trees and shrubs. Forest Park trail map

Spinning wheel Mr. Hastie loved history and had an impressive collection of items portraying this history of Dallas County. As word spread, many local residents began to donate artifacts to add to his private collection. To showcase these many items, Mr. Hastie's museum, portraying the history of Dallas County, opened to the public in 1953. Many of these items remained with the museum when it was acquired by the Dallas County Conservation Board.

The Forest Part Museum Complex has grown to include Baldwin Hall,Wagner Gallery, the Alton School house, the 1860 Grabenhorst log cabin and the Bill Wagner Scale House.

We consider Forest Park to be among the finest small museums in the state, exhibiting natural, cultural, and historical events and artifacts of central Iowa. Permanent displays include early transportation, farm machinery, small hand tools, railroading, a blacksmith shop and much more. The museum often creates or hosts a variety of traveling exhibits on historical, natural and cultural topics of interest.  

Henry Nelson's Dynamo


One of the most popular exhibits at the museum is the electric Dynamo, believed by some to be a perpetual motion machine. It was invented by Henry D. Nelson, a Redfield resident. Mr. Nelson intended to create electricity for a wireless telegraph. It is not known whether Mr. Nelson gave up on his invention or died before he could finish. It is the only one of its kind known in the Central United States.
