In 1990 The City of Minneapolis commissioned artists to create artwork for Nicollet Mall in Downtown Minneapolis. I was commissioned to create 75 manhole covers to replace the covers over 13 city blocks. Thirty more covers for the Northern States Power Company on Nicollet Mall were eventually added. There are 11 different designs which commemorate the state designations and other icons of the state. Included are the the state flower, fish, tree, bird, grain, fruit- the Lady Slipper; the Walleye; Norway Pine; Loon; Wild Rice; Halverson Apples; the grains - Oats, Wheat, Corn, the Timberwolf, the Northern Pike. It is intended that there be discoveries like the worm with the apple or the pheasant in the corn field giving added interest over time. Each are cast iron measuring 26 inches in diameter although the Northern State Power Company covers are 29 inches.
