The 16 Places We Recommend To Find and Dig For New Mexico Geodes in 2024

By Dr. Keith Jackson - Geology PhD


While geodes can be found in many places around the world, New Mexico is particularly famous for its abundance of these geological wonders. In this article, we’ll take you on a journey through some of the best spots to find geodes in New Mexico.

We traveled throughout our state to visit Alum Mountain, La Madera Mine, Sapillo Creek, Luna, and Deming— areas known for their geode deposits. Along the way, we met local experienced rockhounds to learn about the different types of geodes that can be found there and where exactly they’re found in the area.

We’ll share with you our findings and guide you to the most promising locations for geode hunting in our state, in hopes that our exploration will inspire you to get out and discover some of your own.

What Are New Mexico Geodes?

Geodes are fascinating rocks with hollow cavities that are filled with crystals. They can be found in various parts of the world, but our state is a particularly popular spot for geode hunting because New Mexico’s unique geology is ideal for geode formation.

Geodes come in different shapes and sizes and are formed through a geological process that involves volcanic activity, mineral-rich water, and sedimentary rock formations. Its outer layer is usually rough and dull, but its inside shows a stunning display of sparkling crystals, making it a fascinating and beautiful natural wonder that continue to captivate rock collectors and enthusiasts.

Here’s a handy guide on how to tell if a rock is a geode that you can use during your actual geode hunting.

The Types Of Geodes Found In New Mexico

A geode’s value depends on its type and New Mexico is home to different varieties, but its mostly abundant with the following:

  • Agate geodes
  • Amethyst geodes
  • Banded Agate geodes
  • Calcite geodes
  • Quartz geodes
How We Found The Best Geode Locations in New Mexico
When it comes to choosing the best options for finding New Mexico geodes there are plenty of things we consider. Many of the best locations are closely guarded secrets which can make it really difficult for more casual geode hunters to find success. The key factors in our recommendations are:

  • The deep experience and understanding of our team about the area
  • Recommendations from local groups and clubs
  • How easy it is to get the a particular location
  • Safety and potential hazards when collecting
  • Weighing private and public locations
  • The ability for both experienced and novice geode enthusiasts to find great samples

With these factors in mind we’ve been able to put together a fantastic list that just about anyone can use!

The Best Places To Find Geodes in New Mexico

While you may be familiar with some of the popular places for gem mining in New Mexico, not all of them have geodes as well. The locations we are about to share may not be as well-known, but they’re undoubtedly the top picks when it comes to finding geodes here.

Always Confirm Access and Collection Rules!

Before heading out to any of the locations on our list you need to confirm access requirements and collection rules for both public and private locations directly with the location. We haven’t personally verified every location and the access requirements and collection rules often change without notice.

Many of the locations we mention will not allow collecting but are still great places for those who love to find beautiful rocks and minerals in the wild without keeping them. We also can’t guarantee you will find anything in these locations since they are constantly changing. 

Always get updated information directly from the source ahead of time to ensure responsible rockhounding. If you want even more current options it’s always a good idea to contact local rock and mineral clubs and groups

Alum Mountain

Alum Mountain is located in the southern part of our state. It has a fairly rugged terrain, but nothing too intense. It’s basically a massive deposit of volcanic ash that’s been sitting around for millions of years. Over time, groundwater seeped into the ash and deposited minerals that eventually formed geodes.

One thing to note, though, is that the road leading up to the mountain is pretty bumpy, so you might have to take it slow when you’re visiting. All in all, if you’re into geodes, Alum Mountain is definitely worth checking out.

But before you visit, make sure to check first the updated collecting guidelines from the State of New Mexico.

Where we found geodes at Alum Mountain

You’ll be amazed when you find Banded Agate geodes with patterns you won’t find elsewhere on the area surfaces of Alum Mountain.

The tools every geode hunter will need

When you're out looking for geodes having the right tools for the job is very important. You don't need a lot for most trips but there are a handful that are critical and will make your life a lot easier.

We get asked a lot about the equipment we use. Over the years we've found a handful of tools that we recommend to both new and experienced geode hunters which we outline in great detail in our complete rockhounding tools and kit guide. These are quality options that also happen to be relatively inexpensive.

Below are the basic tools that make your life so much easier and save you a ton of time. Check out the full guide to see everything we recommend bringing. One quick note, as an Amazon Associate I earn from qualifying purchases but we try very hard to only recommend gear we would use ourselves and often recommend brands you can't find on Amazon.

At a minimum you should have:

1 - Sturdy rock hammer: The Estwing Rock Pick is our standard

2 - Rugged chisels: Try Kendo' 3-piece Chisel Set

3 - Compact shovel: The Koleiya 28-inch shovel works well

La Madera Mine

A close up look at the geological formation of La Madera Mine

La Madera Mine is up in the northern part of our state, tucked away in the mountains. Its terrain is pretty rough, with steep slopes and loose rocks. This area used to be a copper mine back in the day, but now it’s become a great spot where geodes have formed. It’s also among the best places to find crystals in New Mexico.

Getting here requires a bit of a hike, but if you’re into adventure, it’s totally doable. You have to take some dirt roads and cross a river or two. All in all, if you’re up for a bit of a challenge, La Madera Mine is the place to explore.

In the southwestern part of our state, you will find Sapillo Creek, with its mellow terrain that’s mostly flat areas and some gentle hills. Its water is shallow, so you can wade around in it without too much trouble.

The geology of Sapillo Creek is fascinating. It used to be part of an ancient ocean, and over time, minerals like quartz and calcite formed geodes in the sedimentary rocks. The geodes here are usually on the smaller side, but they come in all sorts of cool shapes and colors.

Visiting here is a piece of cake, as long as you got a sturdy car that can handle some dirt roads. The creek is right off the highway, so you don’t have do too much hiking or trekking.

Where we found geodes at Sapillo Creek

You can usually find Banded Agate geodes just lying around on the creek bed, or sometimes you have to dig a little bit to uncover them. The surest spot to find them, though, is on the creek’s gravels.
