Montana Unit 690 Pronghorn Antelope Hunting Guide

Montana Unit 690 sits in a stretch of prairie and breaks country that draws steady interest from pronghorn hunters, both resident and nonresident, looking for a classic high-plains antelope hunt. Spanning elevations from 2,296 to 6,495 feet across a sprawling 2,559,077-acre unit, this is big, open country typical of the mixed-grass and sagebrush prairie that Montana's antelope herds favor.

What sets Unit 690 apart from many Montana hunting units isn't the terrain — it's the land ownership picture. Public land in this unit sits at just 21%, meaning the overwhelming majority of Unit 690 is private property. For pronghorn hunters, that reality shapes every part of the hunt, from access strategy to whether a DIY approach is even realistic. This article breaks down what the data says about Unit 690, how to apply, and what hunters should realistically expect.

Herd Health & Access Reality

Unit 690 is prairie pronghorn habitat — rolling grassland and low-relief terrain that antelope thrive in, with elevation ranging from valley floor around 2,296 feet up to isolated high points near 6,495 feet. This is exactly the kind of open, big-sky country that makes pronghorn hunting a visual, long-range game: animals are visible from long distances, but covering the ground to get within range is the challenge.

The critical number for anyone considering this unit is the 21% public land figure. With less than a quarter of Unit 690 open to public access, this is not a unit where hunters can expect to show up and find abundant BLM or state land to hunt freely. The majority of the acreage — nearly 80% — is private property, and hunters researching this unit consistently report that access is one of the defining challenges here. Public land pronghorn hunting is still possible in the pockets that exist, but hunters need to identify those parcels well before the season and have a backup plan given how limited the public footprint is.

Given the low public land percentage, Unit 690 should not be treated as a wide-open DIY unit. Hunters without a private land connection, a leased access arrangement, or a booked outfitter will face a materially harder hunt than the acreage total might suggest. Those who do have arrangements with landowners, or who work through a guide, report better opportunities — but that access is not guaranteed and often requires advance planning or existing relationships in the area.

Trophy Quality

Trophy records tied to the counties overlapping Unit 690 show a moderate history of production. This isn't a unit associated with a heavy concentration of exceptional entries, but it isn't devoid of trophy history either — moderate trophy potential means hunters can reasonably encounter good, mature bucks, without the unit being labeled among the state's elite trophy-producing areas. As with all Montana units, trophy-record data is logged at the county level and shared across neighboring units, so the moderate rating reflects the broader region rather than being unit-exclusive to 690.

For hunters whose primary goal is chasing a record-book animal, Unit 690 is a reasonable prospect but not a unit to bank a trophy hunt entirely around. It's better framed as a solid opportunity unit where a mature buck is realistic, rather than a unit hunters should expect to produce elite-class animals on a predictable basis.

HuntPilot Analysis: Is Unit 690 Worth Applying For?

The honest answer for Unit 690 depends heavily on what kind of hunter is asking. This unit presents a real tension: it's a large unit with moderate trophy potential, but access is the limiting factor that will determine whether a tag translates into a quality hunt.

For hunters who already have — or are willing to build — relationships with private landowners in the area, or who plan to work with a licensed outfitter, Unit 690 can be a worthwhile draw. The terrain supports healthy pronghorn activity across its open plains and low country, and the moderate trophy history means a patient hunter glassing the right ground has a real shot at a mature buck.

For hunters expecting an open-access, walk-in DIY hunt purely off public ground, Unit 690 is a tougher sell. With only 21% public land, most of the unit's acreage sits behind fences on private property, and forum accounts from hunters who've drawn tags here consistently describe access as the single biggest obstacle — some describing extensive private holdings and difficulty securing walk-in permission even where public and private land interweave.

The bottom line: Unit 690 is worth applying for if hunters go in with a plan for access — whether that's landowner relationships, block management-style access where available, or a booked outfitter. It is not a unit to draw blind and figure out access after the fact.

Frequently Asked Questions

What is the terrain like in Unit 690?

Unit 690 covers a large stretch of prairie country with elevations ranging from 2,296 feet up to 6,495 feet across its nearly 2.6 million acres. This is classic open pronghorn habitat — rolling grassland and low-relief plains punctuated by higher breaks terrain — well suited to the long-range spot-and-stalk style typical of antelope hunting. The challenge in this unit isn't the terrain itself but the land ownership pattern layered on top of it.

Is Unit 690 worth applying for?

It depends on access planning. The unit carries moderate trophy potential and large acreage, but with only 21% public land, most hunters will need a strategy for accessing private ground — whether through landowner relationships, available access programs, or an outfitter — before applying. Hunters who draw without an access plan often struggle to capitalize on the tag, based on accounts from hunters who've hunted the unit.

How big are the pronghorn in Unit 690?

Trophy records tied to the counties overlapping this unit show a moderate history of production, meaning mature bucks are a realistic goal but the unit isn't among the region's top producers of elite-class trophy animals. Hunters focused on trophy quality should treat this as a solid, not exceptional, prospect.

What is public land access like in Unit 690?

Public land makes up just 21% of Unit 690, meaning the large majority of the unit's 2,559,077 acres are privately owned. This is one of the more private-land-heavy units in the state, and hunters should not expect abundant walk-in public access. A realistic access plan — landowner permission, available access agreements, or a guided hunt — is essential before applying.

Do nonresidents need a guide to hunt Unit 690?

Montana does not impose a state-mandated guide requirement for pronghorn hunters in Unit 690, since the unit carries 0% wilderness designation. However, given the low 21% public land figure, many nonresident hunters choose to work with a licensed outfitter simply to secure access to private ground, not because it's legally required.
