Bloomington Minnesota USA Equatorial Dial Dial 447
An Erickson Monument polar equatorial dial of light granite, approximately 5 feet in diameter and 6 inches thick. The gnomon shaft is steel, 3 inches in diameter, extending from the ground through the dial plate and outward another 18 inches. The base is a simple tier of raised concrete. 24 hours of radiating lines are inscribed on each side of the dial (summer and winter), ending with the hour in Arabic numbers. Time is graduated by half-hour and 5 minute marks. Two equation of time graphs, each about 3 x 5 feet engraved in granite, are set at the north and south ends of the dial, providing corrections from Apr-Sep, and Oct-Mar. [The description to obtain watch time attributes Bloomington's longitude as 93:18 East instead of West. Further, it tells the user to subtract one hour for daylight savings time.] Nearly identical to the Port Arthur Dial, Texas, but without city names located in various time zones.

Hastings Minnesota USA Analemmatic Dial Dial 640
A 5x3 meter analemmatic dial of natural limestone rocks with red flagstone and white limestone for month markers. Arabic hour numerals and month names are sandblasted into the stones. This dial was designed and built as an Eagle Scout project with an original request from the school science teacher, Mr. Rapatz. Roger Bailey of NASS provided technical guidance.
Hibbing Minnesota USA Equatorial Dial Dial 375
An 8 ft high equatorial sundial designed and built by David Aho. Made of welded stainless steel with a brass gnomon and brass equatorial arc dial. The 60 inch diameter equatorial dial is engraved.
Houston Minnesota USA Analemmatic Dial Dial 985
A simple analemmatic dial laid out in a square concrete base. The walkway and hour surrounds are black with white lettering. The hours are Roman numerals run from VI (morning) to VIII (evening). The dial is adjusted for daylight saving time and longitude such that when the sun is on the meridian, the dial shows about 6m after 1pm.
Mendota Heights Minnesota USA Horizontal Dial Dial 1070
This brass horizontal sundial was donated to the school in or around 1908 by the Visitation School class of 1908. It was moved from St. Paul MN to Mendota Heights, MN in 1966 when the school was relocated. In the spring of 2018 it was moved to a protected garden, but sits on the original 1908 pedestal 3 foot (1m) tall and 18 inches (46cm) square. The original dedication engraved into the pedestal is still plainly visible. The dial itself is approximately 12 inches ( 30 cm) in diameter with raised hour lines on the circumference and raised Roman numeral hour marks on the interior from 6am to 6pm. The dial is in excellent condition, but in 2017 a new brass gnomon was cast as a replacement for the missing simple triangular gnomon. The new 1 inch (2.5 cm) wide gnomon is in the shape of a crescent moon. Although aligned with the noon line, this gnomon will never cast a shadow. telling correct time. It is sad that this 114 year old sundial has been reduced to nothing more than an artistic sculpture.
Silver Bay Minnesota USA Horizontal Dial Dial 227
A horizontal dial on the ground, with an hour circle about 12 feet. The gnomon is of steel, about 4 foot high. The gnomon is oriented to magnetic north. It is not an accurate device. Three boulders surround the dial and cut off the shadow much of the time. Gravel hour circle has rocks to mark the hours, but the rocks can be moved and are strewn all about. More suggestive of a dial than a real dial.
