In 1902, Wyoming’s Kirwin mining camp grew to about 200 people; by 1907, a deadly snowslide destroyed the last company buildings and the boom faded

In the early 1900s, people arrived in Wyoming’s remote mountains hoping to build a future from gold, silver, and other minerals hidden beneath the ground. One of the settlements was Kirwin, where families, miners, and businesspeople gathered in a remote valley with the conviction that a booming mining town would soon grow there.

For a brief moment, Kirwin looked like it could become one of the region’s successful mining camps. The town developed actively starting in 1902 when the companies increased their exploration activities, and thus many workers and companies set up their operations in the remote area. The U.S. Geological Survey stated that Kirwin had grown to about 200 people at its peak. However, the mining operations later declined, and in February 1907, a snowslide destroyed the boarding house and storehouse belonging to the last operating company, accelerating the settlement’s decline.

A mountain town built around mining dreams


Kirwin developed around mineral exploration in the Absaroka Mountains of Wyoming, where workers and support businesses gathered near the mining operations. Like many mining communities during the period, Kirwin believed in the capacity of mineral deposits to ensure future prosperity. The town came into being as a result of mineral exploration operations in the area. Workers moved in, as well as other support industries. An isolated town in the mountains was turned into a bustling mining settlement.

Life in Kirwin was tough due to its high location in the mountains. A high location means bad weather, hard transport, and little opportunity to get supplies. However, the chance to create a successful mine made people keep trying to make their lives there.

When a boomtown appeared overnight

At its peak, Kirwin was more developed than its remote mountain location might suggest. The town boasted 38 buildings, including a hotel, boarding house, several stores, a post office, a sawmill, and an assayer’s office for ore testing. Through a stage route, residents could receive supplies from Meeteetse and maintain connections with other communities. The settlement’s location at about 9,200 feet in the Absaroka Mountains exposed residents to harsh winters and difficult travel conditions.

The miners required an array of materials and services, and that created the need for various businesses. Still, mining towns were dependent on whether the mines would yield enough ore. Therefore, Kirwin faced challenges as exploration continued and expectations did not fully match reality.

The snowstorm that changed everything

The decline of Kirwin began to pick up pace in 1907 after a major snowslide struck the mining camp. The snowslide destroyed important structures connected to the remaining mining operations, and mining activities gradually declined afterward. The disaster came at a time when the town was already struggling to maintain its momentum. After the operations ceased, there was not much need for the people to remain in the area. Like many mining camps, Kirwin depended heavily on a single industry, making it vulnerable when mining activity declined. The abandoned buildings became a reminder of how quickly a booming community could disappear because of environmental challenges and economic decline.

A forgotten town becomes a protected piece of history

Ghost towns provide more than a record of failed businesses or forgotten mines. In 1992, the Kirwin property was acquired through conservation efforts and transferred to the Shoshone National Forest, helping protect the historic landscape and remaining structures. The preserved site still contains visible remains of Kirwin's mining era, including cabins, mine openings, machinery foundations, and other historic structures that illustrate how the settlement once functioned. Because of its isolated mountain location, many features survived with relatively little modern development, giving historians and visitors an opportunity to examine an early twentieth-century mining camp in its original setting. According to the U.S. Geological Survey, Kirwin remains one of Wyoming's better-preserved ghost towns, providing valuable evidence of mining methods, community planning, and daily life in a remote settlement where nearly every aspect of the local economy depended on mineral exploration. Today, abandoned mining towns such as Kirwin serve as a source of insight into the lives of communities whose existence depended on resource exploitation. Some structures remained, preserving evidence of the people who once lived and worked there.
