Horsethief Basin Ranch


On the grassland mountains of Montana, immersed deep in the Western landscape, lies the keys to a life. The Old West history and tradition suffusing the handsome expanses in Lewistown, Montana – a certain kind of living keeps people closer to the land.

True freedom requires that – a closeness to something bigger, to an idea that stretches your soul and makes you feel part of a way of life. It transcends everyday complexities, tapping into the touchstones of culture and mystique.

Mort and Donna Fleischer found just that kind of freedom. When on his home ranch in Montana, Mort likes to say he “borrows freedom.” The truth is, he built it. He earned his space in the intense pressure cooker of Wall Street, assembling financial empires for almost four decades. But that world comes at a cost; by the time you realize you’re burning out, it might be too late to rehabilitate your life.

Mort and Donna built their freedom by embracing a way of life defined by authenticity and loyalty, forthrightness and honest work. He found a way to extend his life and amplify his enjoyment of it.

Now he’s offering that to you. It’s not the chance of a lifetime.
It’s the chance for a lifetime.

A winding lane flanked by miles of lush, green grass. This is the West the way it was, the West of cowboys and cattle drives, beautiful wildflowers and abundant wildlife. Here, people are still riding for the brand and the mountains still hold untamed promises.

This is vastness as a way of life, the land as a means of defining your place on earth.

Horsethief Basin Ranch encompasses some of the strongest grass country Montana has to offer. The Ranch can conservatively support 400± cow/calf pairs plus replacement heifers. Additional yearlings can be run on a year to year basis depending on rainfall and grazing management. The Ranch has 500± tillable acres currently all in alfalfa and alfalfa/ grass hay mix. 400± of the tillable acres has been freshly renovated and are in peak production years. The Little Snowy Mountains on average get stronger and more consistent rainfall than surrounding lower elevations, thus providing needed moisture for hay and grazing pasture production.

In the past, Horsethief Basin has been run as a commercial cow/calf operation. Cattle are fed hay throughout the winter months and turn onto Summer pasture after branding in late Spring. The cattle go on a grazing rotation until Fall, when the calves are weaned and shipped. You won’t find sage brush or prickly pair cactus at Horsethief Basin Ranch, and the current owner has been diligent on weed management. The Ranch has a very efficient and well designed steel pipe corral system. All interior and perimeter wire fences are in good condition and consistently maintained.



Big Spring Creek is a stream of extraordinary beauty and is a superb fishery. It is a great nymph and dry fly stream, but wet flies also work well. Open to year round fishing, it is fishable when many other streams are blown out from runoff. A wade and walk stream, Big Spring Creek is not a float and fish stream. It is easily wadable, but chest waders are recommended. If you wade wet, shorts are not recommended due to brush, thorns and sun reflection. Originating seven miles southeast of Lewistown where it bubbles out of the ground near the state trout hatchery, Big Spring Creek runs almost twenty-six miles to where it joins the Judith River. With nine state fish and game public access sites within ten miles of town, Lewistown is one of the few towns of some size (population approximately 6,500) that you can often catch fish within the city limits.


Lewistown sits in the center of antelope country. All of the pronghorn hunting is restricted to permit only, but several of the surrounding areas have liberal quotas so interested hunters have a reasonable chance of drawing a tag. Central Montana antelope hunting gets you out on the wide open plains of the west during one of the prettiest times of year. This is an excellent place to attempt the challenge of taking a pronghorn with a bow. For the hunter looking for the ultimate challenge, you can spot-and- stock. Either way, the antelope population is rebounding in our area, access is readily available via public lands (mostly BLM), and the challenge awaits!


Many opportunities exist in Central Montana for hunting elk and hunters are sure to find a deer that meets their expectations. Archery opens in early September and continues until mid- October. There is a week hiatus of closed season before the rifle season opens in later October. Crossbows are not allowed during archery season, but one can hunt elk during rifle season with archery equipment, including crossbows. Most all of the elk hunting is by permit only. Because elk herd numbers are above or at management plan objectives, the Montana FWP has instituted a number of special hunts to try and control the population. Archery Only Elk, 900-20 Region has an 82% Draw General Season Elk, 411-20 Region has a 19% Draw Drawing odds greatly increased for landowners via the Landowner Preference with Montana FWP.


The upland bird hunting opportunities in central Montana are abundant, yet varied. Our region has excellent habitat for 2 species of mountain grouse (ruffed and blue), 2 species of prairie grouse (sharptails and sage), Hungarian partridge and pheasants.
