Badger Calculator

The Badger Calculator was built and branded for Western Lands Preservation (WLP) — a company founded in 2020 by Steven Whitney. Steven was 15 years old then, with a mission to preserve wildlife and wild lands across the Western United States. WLP owns a 30-acre preserve in the Oquirrh Mountains in Utah and sells nature-themed products in shops across 15 states.

The calculator follows the WLP forest green theme color and displays the badger mascot, hand-drawn by Steven himself. Click the badger and the calculator opens the Badger Credo.

The Badger Story

The mascot was born on a mountain trail in the Wyoming backwoods when Steven encountered a badger peering out of its den — furry, dark brown with white stripes, with curious eyes that seemed to say "Who are you?" That moment of curious innocence in the wild became the inspiration for Western Lands Preservation and its nature-themed products. You can read the full story at Badger Story.
