Montana Unit 670 Pronghorn Antelope Hunting Guide

Montana Unit 670 sits in the sprawling prairie country of the state's eastern reaches, offering pronghorn antelope hunters a mix of public and private land across a vast landscape defined by open sagebrush flats and rolling grassland. With elevation ranging from just 2,057 to 3,313 feet, this is classic pronghorn country — flat-to-rolling terrain where speed-goats can be spotted from long distances and hunters rely on glassing and stalking tactics rather than heavy vertical terrain navigation.

The unit spans roughly 2,639,375 acres, an enormous footprint that gives hunters plenty of room to spread out and find pockets of antelope away from crowded access points. Public land makes up 53% of the unit, which puts the majority just barely on the public side of the ledger — enough for DIY access, but hunters should expect a real mix of public parcels and private ground woven together across the landscape, meaning careful map work and permission-seeking will factor into a successful hunt.

Unit 670 carries no designated wilderness acreage, which means logistics here are straightforward compared to mountain units — there are no stock-and-pack considerations or wilderness guide mandates to think through. This is vehicle- and foot-accessible prairie hunting, well suited to hunters targeting pronghorn with a good spotting scope and a plan for covering ground.

HuntPilot Analysis: Is Unit 670 Worth Applying For?

Unit 670 is a solid consideration for pronghorn hunters who value open access and a workable draw process over guaranteed trophy production. The 53% public land figure means hunters have a real shot at finding huntable ground without needing to lease or lock down private access, though that also means nearly half the unit is private, so scouting ahead of the season — and understanding boundaries — will matter for a successful DIY trip.

The counties overlapping this unit carry a moderate history of trophy records, meaning some quality bucks have come from this general area over time, but hunters shouldn't plan a trip banking on an exceptional buck. This is a unit where hunters can reasonably expect a fair look at pronghorn numbers and a chance at a solid, representative buck for the region, without the sustained, decades-deep trophy pedigree seen in the state's very best antelope country.

For nonresidents, the appeal of Unit 670 is largely about opportunity: a low-elevation, low-complexity landscape that doesn't demand technical terrain skills, paired with an application process that — while requiring careful budget planning given nonresident fees — is far more approachable than many Western big-game draws. Residents looking for antelope opportunity close to home will find this unit's flat terrain and expansive acreage make for efficient scouting and hunting once tags are in hand.

Overall, Unit 670 is worth applying for if a hunter's priority is opportunity, accessible terrain, and a fair public-land base, rather than a bucket-list trophy pursuit. Hunters chasing a serious record-class pronghorn should weigh this unit against others with deeper, more consistent trophy history before committing points or application dollars.

Trophy Quality

Trophy data for Unit 670 points to a moderate history of quality antelope coming from the counties that overlap this unit. That means there is a track record of good bucks in the region, but it isn't among the handful of units in the state with the deepest or most consistent trophy pedigree. Hunters can reasonably hope for a solid, mature buck, but should treat a genuinely exceptional or record-class pronghorn as a bonus rather than an expectation.

It's worth remembering that trophy records are logged by county, not by hunt unit boundary, so any historical quality associated with this area is shared with neighboring units that overlap the same counties. A hunter targeting Unit 670 specifically for trophy potential should factor in that the record-book history reflects a broader geographic pool, not animals confirmed to have come from within this unit's exact lines.

Access & Terrain

Unit 670's terrain is about as accessible as pronghorn hunting gets in Montana. Elevations run from 2,057 feet up to 3,313 feet — a modest range that translates to gently rolling prairie and open flats rather than steep mountain topography. This kind of country rewards hunters who can glass long distances, identify herds early, and plan a stalk across open ground, rather than those relying on timber cover or elevation gain for concealment.

At 2,639,375 total acres, this is one of the larger hunting units a pronghorn hunter will encounter, and the scale means hunters willing to drive and walk can put real distance between themselves and other hunters, even during pressured periods of the season. With 53% of the unit classified as public land, there's a workable base of public access, but the remaining 47% is private, so hunters should expect checkerboard ownership patterns typical of eastern Montana prairie country. Successful hunters generally spend time before the season studying land ownership maps and identifying legal access points, since public and private tracts can sit adjacent to one another without obvious boundary markers on the ground.

There is no wilderness acreage in Unit 670, which simplifies access considerably — no special permitting, no stock restrictions, and no guide requirements tied to wilderness status. This is a unit where a truck, a good set of optics, and solid map work go a long way. Hunters using HuntPilot's mapping tools can overlay public land boundaries directly against the unit to identify likely access points and plan routes before ever setting foot in the field.

Frequently Asked Questions

What is the terrain like in Montana Unit 670? Unit 670 is prairie and grassland country with a modest elevation range of 2,057 to 3,313 feet. Expect open, rolling terrain typical of eastern Montana pronghorn habitat — long sightlines, sagebrush flats, and gentle topographic relief rather than steep mountain terrain. There is no wilderness acreage in the unit, so access is generally straightforward for hunters comfortable with prairie-style spot-and-stalk tactics.

How big are the pronghorn in Unit 670? Trophy records for the counties overlapping Unit 670 show a moderate history of quality antelope. Hunters can reasonably expect solid, representative bucks for the region, but this area doesn't carry the deep, consistent trophy pedigree of Montana's top-tier antelope units. A genuinely exceptional buck is possible but shouldn't be the expectation going into the hunt.

Is Unit 670 worth applying for? For hunters prioritizing accessible terrain, a workable public land base (53%), and a straightforward application process, yes — Unit 670 is a reasonable choice. It's less compelling for hunters solely chasing top-end trophy potential, given its moderate rather than exceptional trophy history. It's best suited to hunters who want a solid pronghorn hunting experience with meaningful public access rather than a guaranteed record-book pursuit.

What is harvest success like in Unit 670? Harvest statistics are not available for this unit in the current data. Hunters should check HuntPilot's Montana unit pages or the state wildlife agency's harvest reports for the most current success-rate figures before planning a trip.

Do nonresidents need a guide to hunt pronghorn in Unit 670? No. Unit 670 has 0% wilderness acreage, so Montana's guide requirements tied to wilderness access do not apply here.
