This Is Where To Find Geodes In Colorado
You’re out for a hike and something on the path catches your eye. You see a small fossil, a shiny stone or a glimmering crystal and, naturally, you pick it up. Soon, the ground becomes a treasure trove of things to be looked at, turned over, scrutinized and pocketed. Once this happens, there’s no turning back. Rock-hound fever has struck.
For inveterate hikers and trekkers who explore Colorado’s mountains and forests regularly, these surprises add another dimension to the experience: That pretty, little green stone may be jade or amazonite; what looks like glass that washed out of a hillside might be a quartz crystal; the round, rough-hewn rock could be a geode.
Colorado offers an abundance of minerals, gemstones, crystals and fossils to anyone willing to go out and look for them. For the casual collector or the obsessed amateur, there’s a little something for everyone, just about everywhere. It’s a matter of paying attention.
Once the newbie hound is hooked, it helps to understand the terms rock and mineral, and how the two are related.
First, there’s no such thing as “just a rock.” A rock is more than an aggregate of minerals. Rocks are the history books of ancient geologic times. They include limestone, granite, sandstone and shale, as well as gravel beds, clay and even — can you believe? — the permafrost of Siberia. In fact, any deposit that makes up the Earth’s outer crust. And rocks are the preservers of fossils that once lived when Colorado was a vast sea.
But what about those other treasures hidden in rocks — the minerals that are at the heart of a collector’s expedition? A mineral is a naturally occurring, inorganic solid, and has its own characteristic crystalline structure. Gems, then, are the flowers of the minerals that have ornamental value because of their beauty, durability and, occasionally, some degree of rarity.
Colorado ranks among the most strongly mineralized areas in the world, and it’s especially noted for alabaster, amethyst, lapis lazuli (blue sapphire), topaz and turquoise. Its most characteristic gem is amazonite, the bright green mineral that is often mistaken for jade. But, hey, you don’t know what’s going to turn up when you’re out in the woods.
The Colorado landscape has changed dramatically in the last 10 years, with public lands becoming private, claims being staked and roads leading to closed gates. But the fun is still there if you know where there is public access. And one of the best resources is membership in the Colorado Mineral Society (CMS).
CMS has access to areas not always available to the beginner going it alone, and can help guide newbies as to where to go and what to look for. After a few field trips with seasoned explorers, you will discover how to recognize crystal- and gem-bearing rocks, as well as learn about local geology and topography.
Top 5 Rockhounding Spots In Colorado
Wolf Creek Pass: US 160, also known as Wolf Creek Pass, can be a challenging drive. To get to Wolf Creek Pass, the driver must be wide-awake as the road can deceive you. Always be alert of your speed. The area is remarkable for those searching for rocks. Extensive lava flows cover much of the southwestern Mineral County. If you travel four miles west of Wolf Creek Pass, you will discover an outcrop of zeolite.
Whitewater: Whitewater is one of the few locations where you can find geodes in Grand Junction. They are generally lighter brown in colored mounts that line the hillside. You might need to work to find your geodes, as you will probably need to dig to find unbroken pieces. You will discover this rock paradise 10 miles south of Grand Junction.
Felch Creek: Felch Creek will provide you with agate, geodes, and jasper. It is one of the few locations where true botryoidal fluorite specimens can be found. This stream is close to Oil Well Flats.
Houselog Creek: Houselog Creek is located in Saguache County at a distance of 12 miles from Saguache. Houselog Creek usually offers its diggers great rewards, so be sure to take your digging tools and large buckets for your haul. Your reward will be a treasure trove of agate and chalcedony. The site has received an overall rating of eight out of 10 from collectors.
Garden Park: Garden Park is located near Canon City in Fremont County. You will find the area rich in geodes and quartz. The area also has an interesting history. It was formed by the erosion of sedimentary rocks. The uplift of the Rocky Mountains has caused some distortion. The formation has basically divided the area into a lower and upper unit. The lower is composed mostly of green and gray mudstones. The upper is composed mainly of red mudstone, with lesser amounts of yellowish, often tabular sandstone.
The five sites noted will offer the beginning rock collector and the more advanced collector significant discoveries to add to their collection.
