About the Museum:
The Holden/Marolt Mining & Ranching Museum explores the industrial and agricultural history of the area. From mining to railways to ranching, the past comes alive at this pastoral museum that sits on the site of the largest industrial complex in the history of Pitkin County, the Holden Lixiviation Works. The historic Zupancis homestead was recently moved from Aspen’s downtown core to the property by the City of Aspen. The buildings, including a miners-cabin-turned-Victorian-home, a barn and an outhouse, are being restored to help tell the story of the Quiet Years and immigrants who helped shape the area. The Holden/Marolt Museum is directly adjacent to a public bike trail near the entrance to Aspen on the Marolt Open Space.
In 1891, the Holden Lixiviation Mill sprawled over 22 acres at the edge of Aspen, boasting state-of-the-art technology and industrial design. Just 14 months after the new plant opened, Congress demonetized silver and the mill went bankrupt. Mike Marolt purchased the property for a dollar in 1940 as a family ranch. This site is unique. It tells the stories of both Aspen’s mining and ranching heritage.
Founded as a silver mining camp in 1879, by I890 Aspen was the single largest silver producer in the US. With a population of over 13,000, Aspen was the third largest city in Colorado. Only Denver and Leadville were larger.
Aspen’s big news in 1891 was the building of the Holden Lixiviation works on the west side of town. The newspaper declared that “the sweet day dreams of those who have longed to see Aspen a great city are about to be realized.” Completed just fourteen months before Congress repealed the Sherman Silver Act, the plant never cleared a profit and went bankrupt almost immediately. It was one of only eighteen plants built world-wide to utilize the experimental Russell Lixiviation process to refine low grade ore.
The Russell Lixiviation process used crushing, heat, and chemical salts to refine silver from ore as low grade as ten ounces per ton. (Aspen ores averaged 400 to 600 ounces of silver per ton, but much low grade ore had to be discarded.) The fumes from the plant’s Stetefeldt furnaces were emitted from the main smoke stack 165 feet high, reputed to be the highest stack in the state.
One of the reasons that the Sampling building still stands is because it was built to hold large machinery that crushed and pulverized the ore.
By 1904, after several attempts to run the Holden Works as a concentrator (a process of discarding some of the worthless material to make the low grade ore cheaper to transport), the plant was closed. During the quiet years the Marolt family ranched near the mill. In 1940 they purchased the mill for one dollar, and combined it with the Midland Ranch to form the Marolt Ranch. The Marolts raised sheep and cattle and planted potatoes. By the late 1950’s, the Marolts started selling off parcels of their land, due to decreasing Forest Service grazing acreage, financial strains of the kid’s college educations, and Mike Marolt’s deteriorating health.
In the 1940s, the site was considered by the US Army as a training camp for the 10th Mountain Division, however, Camp Hale was established over the surrounding peaks near Leadville for that purpose. Nevertheless, maneuvers frequently brought them to the Ashcroft area and the soldiers soon found Aspen for their “rest and relaxation.” Many 10th Mountain veterans returned following WWII to build Aspen into the world class ski resort that we know today.
The Holden site, once a symbol of Aspen’s industrial might, became the symbol of a vanishing ranching economy as skiing fueled the rebuilding of Aspen.
Farming and Ranching
Why They Ranched
As soon as the first prospectors entered the valley in 1879, they created a demand for food. The use of pack animals created an even greater demand for crops as they needed to be fed. Many ranchers started out mining but switched to ranching after tiring of the difficult miner’s life. When silver was demonetized in 1893, mining became less profitable.
Roundups occurred twice a year, in the spring and in the fall. They were necessary to separate herds belonging to neighboring ranches, to brand them in the spring and ship them off to be sold in the fall. Several ranches were usually grouped into districts by the Cattleman’s Association. Cowhands from each outfit assisted with the roundup.
The roundup was the hardest time of year for cowboys. Their day began at 4:00 a.m. when they broke up into work details. Some would scour specific drainages and areas, while others herded the cattle together before meeting at an appointed place. They completed this work before noon. Once all of the cattle was rounded up, each ranch had to separate out their cows. Newborn calves were roped and then branded.
In the spring, the cattle was then driven to the summer range where they would stay for the summer. In the fall, the cattle roundup was usually smaller. The main purpose was to tally the herd and record information on ranchers’ logs. The cattle was then driven to the nearest railhead to be sent to eastern markets. Now cattle are shipped by truck or train.
Historian Larry Fredrick holds up a silver dollar to show the class what all the fuss was about.
