About This Spring
## Overview Elmer's Fountain is a year-round public drinking spring located in the small mountain town of Mullan, Idaho, nestled in the Silver Valley of Shoshone County along the historic Interstate 90 corridor near the Idaho-Montana border. This roadside spring has been a welcome stop for travelers passing through the Bitterroot Mountains, offering a refreshing taste of natural spring water in a forested setting. Mullan itself is one of Idaho's oldest mining towns, founded during the silver and lead mining boom of the late 1800s, and the spring reflects the region's deep connection to its abundant mountain water sources. Visitors have reported that the water from Elmer's Fountain tastes clean and refreshing, and it has historically been used as a drinking water source by locals and road-trippers alike. ## Directions 1. Travel east on **Interstate 90** toward Mullan, Idaho. Note that the spring is accessible only from the **eastbound** lanes of I-90. 2. Watch for **Mile Marker 66** — this is your landmark for the dedicated exit/on-ramp that provides access to the spring. 3. Take the exit at Mile Marker 66 and look back into the trees off the roadside. The fountain is tucked among the trees and can be easy to miss if you're not watching for it. 4. The nearest address is **125 Earle Street, Mullan, ID 83846**. GPS coordinates: **47.470208, -115.801825**. *Note: If you are traveling westbound on I-90, you will need to find a turnaround point and approach from the eastbound direction to access the spring.* ## What to Expect Elmer's Fountain is a classic roadside spring — simple, unassuming, and tucked back among the trees just off the interstate. The spring flows year-round, making it a reliable stop regardless of the season. The setting is wooded and quiet despite its proximity to I-90, offering a brief escape from the highway. Because the fountain is slightly hidden in the tree line, keep a sharp eye out after exiting at Mile Marker 66. The area around Mullan sits at roughly 3,300 feet in elevation in the Coeur d'Alene Mountains, so expect cooler temperatures and the possibility of snow during winter months. There are no formal facilities at the spring itself, so plan accordingly. The town of Mullan is just steps away if you need additional services.
