Trail Overview

This challenging two-track technical trail is a dramatic traverse defined by extreme post-fire devastation. The track constantly alternates between sections of loose dirt, DG, and exposed granite rock. The sparse canopy reveals a stark forest of silver and blackened standing snags. The 1.4-mile traverse demands constant attention to line choice, but the quick transit time of under 17 minutes confirms that a capable vehicle can handle the rock steps quickly. This is a memorable exploration into the high country's raw, recovering landscape.

Difficulty

Rated 4 (Challenging Rock Steps): The trail maintains this rating due to the pervasive rock steps and uneven granite tread that demand robust vehicle protection. While the time confirms moderate speed is possible, Four Wheel Drive is highly recommended to crawl safely over the larger obstacles and manage engine braking during the descent, minimizing impact. High clearance is mandatory to avoid undercarriage impact.
