Preservation North Dakota, a private nonprofit coalition, wants the public to submit nominations for its annual "Three Most Endangered Properties" list.

The list is intended to draw attention to irreplaceable historic, architectural, cultural and archaeological resources in North Dakota that are in imminent danger of being lost, according to Dale Bentley, the group's executive director.

Preservation North Dakota works to raise public awareness about the plight of historic prairie churches, rural farm sites, historic barns and boomtown storefronts, and to develop possible solutions to save them.

To qualify for the "Three Most Endangered" list, a site must have historical, architectural or cultural significance that is in danger of demolition, substantial alteration, or deterioration through neglect or vandalism. Usually, properties selected have local grassroots supporters trying to preserve them.

The "Three Most Endangered" list was first announced in the spring of 2000. A few sites that have been listed in the past include the Backhaus farm site in rural Emmons County, Old Main on the MSU-Bottineau campus, Pleasant Valley Church, rural Park River, Coghlan Castle near St. John in Rollette County, the Hutmacher farmstead near Manning in Dunn County, and the Plaza Community Museum, Plaza.

Submit nominations to Preservation North Dakota, Box 28, Buffalo, N.D. 58011-0028. For more information, call 701-633-2763. To receive an e-mail form, contact bankers@ictc.com.

The deadline for nominations is Tuesday. The list will be announced April 29 at Preservation North Dakota's annual conference in Fargo.
