The Forest Megaphone
Discover Nature, Sound, and Learning in North-Central Minnesota
The Neilson Spearhead Nature Preserve, located near Bemidji, Minnesota, offers visitors a unique opportunity to explore forests, lakes, and wildlife habitats. Central to the preserve is the Forest Megaphone, an innovative acoustic installation that amplifies the subtle sounds of the forest, creating an immersive listening experience.
Forest Megaphone: Listen to the Forest
The Forest Megaphone is a large wooden, conical acoustic structure. Unlike traditional megaphones, it collects and amplifies ambient natural sounds such as:
Birdsongs and insect calls
Wind rustling leaves
Water flowing in streams and lakes
Visitor highlights:
Step inside or stand behind it to hear nature like never before
A contemplative spot for reflection, mindfulness, or art activities
Created in 2025 by Bemidji State University senior capstone students using locally donated, pressure-treated wood
Located along the circuit trail around Spearhead Lake, accessible by foot or paddle
