A grand example of the fine craftsmanship completed by those who found work with the Works Progress Administration (WPA) during the Great Depression, the Walsh County Courthouse has retained a high level of historic integrity. Exhibiting a great degree of artistic quality in its decoration, the building is significant in North Dakota’s architectural history as the only courthouse in Art Deco styling in the northeastern part of the state. Dedicated in 1940, the building’s design is a showcase of a diverse collection of metals, woods and marbles. The courthouse is open 8:00 to 12:00 and 12:30 to 4:30 Monday thru Friday.
This cache is part of the PWHT. The trail is comprised of several geocaches placed at various historic sites in both Pembina and Walsh Counties and rewards are available to those visiting at least 5 geocaches in one or 5 in each county. Geocaches have been hidden in historical locations within each county. When you find a geocache, record the GC code, date, and the passport code from the actual geocache container. When you have found and recorded five (5) geocaches in a county, you can turn in your passport to receive that county’s commemorative coin. To document successful "finds" of geocaches on the PWHT, you will need the passport, which can be downloaded at http://www.redriverrc.com/wp-content/uploads/2017/02/passport-v.2.pdf . This passport includes instructions for claiming the rewards.
