In 1899, Dr. Morton Elrod arrived in Bigfork after steaming up the full length of Flathead Lake from Polson. Drawn by the area’s sheltered cove, he saw Bigfork as an ideal—though temporary—base for a field station dedicated to studying the region’s unique biology. At the time, Bigfork was little more than a scattered collection of buildings and a few notable settlers, including Everit Sliter. To explore the lake’s depths, Elrod bought a small fold-up boat from Sliter, naming it The Daphnia. Using only a rope and weighted line, he painstakingly took soundings —some reaching nearly 400 feet along the eastern shore. These efforts doubled as reconnaissance for a permanent biological station, which he later established in Yellow Bay.
Until then, Elrod and his students built a scientific legacy from their humble outpost on Bigfork Bay. With limited equipment and candlelit labs, much of their research happened outdoors. They explored Swan Lake, the Swan Valley, and the Mission and Swan Ranges—laying the foundation for understanding how these ecosystems connected to Flathead Lake.
Despite its modest scale, the Bigfork station drew renowned naturalists and conservationists, enhancing the region’s ecological importance. By 1909, with enrollment rising and interest growing, Elrod relocated the Flathead Lake Biological Station to Yellow Bay—still accessible only by steamship, as no road reached it until the 1930s.
Though it hosted the station for just over a decade, Bigfork remains proud to be the birthplace of Dr. Elrod’s vision for research, exploration, and education first took root on the shores of Flathead Lake and a vision that continues to shape the study and stewardship of Montana’s natural world.
