While you don’t necessarily need a jeep to get there, it’s still awesome!! A geology professor at Utah Valley University told me the greatest chance of finding topaz is in the spring. Regardless of the season i can’t seem to find the evasive mineral anywhere but in under the sagebrush where other’s have walked past. Anyone been there? 4 millimeter long fragments in the stream-beds just aren’t as exciting… Anyway, I noticed some nearby trails that might be fun for a jeep… i’ll be testing them out next time I go.
