Denver Gem & Mineral Guild

Collecting Sites - Colorado

We receive this question all the time from out-of-state visitors – “I’ll be visiting your area soon and was wondering where I can hunt for minerals?”

Yes, Colorado is rich in minerals and has long been a popular place for rockhounds. Private land will of course require permission from the land owner.  National Parks and Wilderness Areas are off-limits to collectors, but Colorado has plenty of  Forrest Service and BLM lands that are generally open to rockhounds. However, many of these, such as Devil’s Head, have been heavily picked over for years and may require considerable time (days/weeks) and hard rock digging to find anything. Other areas like Mount Antero which used to be open to collectors were wildly popularized by the Prospectors TV show in 2013-2016 and are now totally blanketed by private claims.

If you will be visiting for a short time, here are our top suggestions for where you can still go rock collecting, have a good time, not get run off at gunpoint, and have your best chance of actually finding something to take home and add to your collection.

PAID Gold Panning areas around Colorado

If you don’t have experience with gold panning or you don’t even own a gold pan, then you might want to start at one of Colorado’s great paid sites which offer instructions and equipment:

Bachelor Syracuse Mine – Mine Tours and Gold Panning, Ouray CO, call for reservations.

Mollie Kathleen Gold Mine Tour – Cripple Creek CO, descend 100 stories below the surface and see gold veins in their natural state. Free gold ore sample included (but no panning here).

Hidee Gold Mine – Tour and/or Panning, Central City CO – Panning package includes lessons, samples, and gold ore.

Argo Mill – Tour and Gold Panning, Idaho Springs CO – Panning is available even for those who do not want the tour with guaranteed placer gold.

Florissant Fossil Quarry – the Florissant Fossil Beds National Monument is one of the world’s richest and most diverse fossil deposits which includes petrified tree stumps up to 14 feet wide, plus numerous other plant and insect fossils. Of course, collecting is not allowed in the park, but just outside the park, you can collect at the private Florissant Fossil Quarry. Many fine specimens found at this quarry are on display at the Denver Museum of Nature and Science in Denver and at the National Monument. They provide tools, personal instructions, and access to freshly excavated shale from the Florissant Formation.
NOTE! – The owners of the quarry have indicated they may retire at the end of 2024. It is not known what will happen with the site after that. So if you want to go to this site – GO NOW.

Dinosaur Digs and Expeditions – The Museums of Western Colorado offer a variety of dinosaur digging opportunities. Participants are allowed to dig under the museum’s collection permit. Sorry, you may not keep what you find. All materials are returned to the Museums for research and display. But you can take lots of pictures and make your contribution to science! Advance registration is required.

Hartsel Blue Barite – This is a long-time favorite with Colorado Collectors. On my first visit 20 years ago, I found it via one of the Colorado mineral guidebooks when I happened to be in that area. As we approached the area we asked ourselves – “what does blue barite look like?” When we opened the car door and looked down at the ground we said – “oh that’s what it looks like!” It was everywhere! You will have no trouble finding it. It’s only a matter of finding your best pieces.  This is now a fee site. You will need to go to the Bayou Salado Trading Post, 12561 Hwy 24, Hartsel CO 80449 (location & hours)  to pay a small fee and sign a waiver before going to the site. At the Trading Post they can give you directions to the site and suggestions on finding the best material.

Limonite Pseudomorphs after Pyrite –  White River National Forrest. From Interstate 70, take the Dotsero exit and head west on the frontage road for about 3000 feet. From the traffic circle head North on Colorado River Road for about two miles to a left on Coffee Pot Road (600). Continue on road 600/140 for about 18 miles (50 minutes) to the White River National Forrest. (If using a GPS, set Coffee Pot Spring Campground as your destination.)

These brown cubes of limonite can be found for miles on both sides of the road within the National Forrest.  Pyrite has weathered out of the bedrock (limestone) in this broad area and the pyrite has weathered into limonite, but retained the original pyrite shape.

Limonite is actually a general term for a mixture of iron oxides including Goethite, Hematite, Hisingerite, Jarosite, Lepidocrocite, and Maghemite. Quarter-inch cubes are common here, and cubes up to one inch may be found. The largest crystals with the best crystal shape are the most prized.

The Last Chance Mine – Mine Tour, Collecting & Free Museum – located at
504 Last Chance Mine Rd, Creede, CO 81130

Come experience the mine as the old timers did in 1891.

Looking for more information on where you can collect in Colorado? Here is a list of Rockhound Guidebooks for Colorado, along with where you can borrow them – for free.  For some of the listed books I have also included the Amazon link, not necessarily so that you can buy them, but so you can use the Amazon “Look Inside” link which will allow you to view the table of contents to see which sites are covered in each book (and sometimes much more). Note that the older the book is, the more likely that availability or access information may have changed for the listed sites.

Note that any Colorado resident may apply for a Denver Public Library (DPL) card – you do not need to be a resident of Denver. The Same applies for the Jefferson County Public Library (JCPL). Once you have your library card you can reserve any book online and then pick it up at the branch that is most convenient for you.  Some of these books are available as Ebooks through the Axis360 system and you can download them to your device without ever needing to go to the library!  A few of these books are also available from the DGMG Library for Guild members to check out.
