Topaz Mountain is part of the Thomas Range in Utah. The trip takes about 2 1/2 hours from Salt Lake City. The closest town to Topaz Mountain is Delta. Heading South on I-15 you take the second Nephi exit(225) and head West on HWY 132 for 33 miles. Turn left and head South on HWY 6 for 6 miles until you reach Brush Wellman Rd. Turn right onto Brush Wellman Rd and drive 38 miles. You will see the sign to turn off the road, North to Topaz. This part is not paved. Head west once you reach the range for about .6 miles and enter Little Valley Wash. If you would like to try other spots just remember to look for the Rhyolite. Ask the old timer who has a couple trailers up there. He has a claim and knows everything about the area. A good person to make friends with. Don't look like a novice and just break out the crystals. It's best and more valuable to take them as specimens, inclusion to the Rhyolite. The Rhyolite is white rock and you want to open the soft pockets. Look for vegetation growing from seams in the rock for your best chance to find the Topaz. Red Beryl can sometime be found as well. This stuff is rare and sells for about 2K per faceted carat. Again, better collected as a specimen. My cell phone actually got a signal out there and I was able to call home to Piper. I took the Mazda 626 but a truck with better clearance would have gotten me further. 4X4 isn't necessary. Agate, Apache Tears and Geodes aren't far so check out additional collection sites while in that county.
