Due to the depressed economic conditions of the early 1890s, the mining company was never really successful, and in 1895 the "Helena Syndicate" withdrew its support. In addition, in April 1895 there was a disastrous mine explosion from which the Company never completely recovered. However, mining was continued on a limited basts until 1903 when the mine was closed. In 1907 the mine was sold to the Seattle Lighting Company.
In order to expedite the shipment of coal from the Blue Canyon mine, some of the stockholders of the Blue Canyon Coal Mining Company, including the "Helena Syndicate", organized the Bellingham Bay and Eastern Railroad. As mining diminished and was replaced by lumber traffic, the line was improved and extended. Finally in 1901 and 1902, the line was extended to connect with the Northern Pacific Railroad at Wickersham. Shortly thereafter, on October 10, 1902, the "Helena Syndicate," which controlled the stock of the company, transferred ownership to the Northern Pacific Railroad.
The correspondence of both the Blue Canyon Coal Mining Company and the Bellingham Bay and Eastern Railroad should be consulted in working with either group. One letter often contains material related to both companies since the ownership was almost the same.
