The painting is titled "Seven Sisters Mt., Skeena River, BC," which indicates that it depicts the Seven Sisters Mountains as seen from the Skeena River in British Columbia. The work was completed in 1971, as indicated by the date it was painted, July 27, 1971.

The painting is an oil on board, a traditional medium, measuring 12 x 16 inches. It presents a landscape scene with a focus on natural beauty. The composition features the prominent Seven Sisters Mountain range in the background, capped with snow, suggesting the time of year might be late spring or early fall when snow is still present on higher elevations but the lower land is free of snow.

In the foreground, there appears to be the Skeena River, characterized by its vibrant blue color which suggests the clarity and purity of the water. The riverbanks are adorned with lush greenery, indicating the fertile nature of the area. The technique appears smooth with well-blended paint, capturing the serene atmosphere of the location.

The painting is signed on the bottom right, which is a traditional location for artists to place their signature. This work, given its size and subject matter, could be described as a plein air painting, where the artist paints the landscape outdoors and on-site. The artwork seems to evoke a sense of peace and the grandeur of the Canadian landscape, reflecting Collier's interest in and dedication to the natural world.
