The official presentation of awards in the Ernst Peterson "Photograph Montana" Contest will be at 6 p.m. Thursday at the Ravalli County Museum.

Awards will be made in each category, along with Best of Show awards. There are divisions for both amateur and professional. The photos were submitted last month and went on display on the second floor of the museum May 1.

The presentation will be part of the weekly Thursday Late Opening and Free Admission event at the Hamilton museum. The building is the former Ravalli County Courthouse and has exhibits of local history and an extensive archive of papers and photos, including the complete collection of famed Bitterroot photographer Ernst Peterson.
