The following guide introduces you all the steps to follow, step by step, to complete 100% the Alaska Mountain River map. So that means completing all missions, unlocking all achievements, and collecting all vehicles and upgrades. Of course, if you don’t want to spoil the game, I invite you not to read it.

Note that this guide is a translation of the excellent work done by -Stuart- on Reddit, whom I thank greatly for his work and for accepting that I translate it for the Francophone community of Snowrunner. You will find the original article at this address.


In the guide you will find suggestions for trucks to use. This choice is very subjective, ceveryone has their favorites. In this guide, we only use two main vehicles. However, you will accumulate a lot of money as you progress, so feel free to experiment. As a reminder, you can buy and then resell vehicles and upgrades for the same price. So you don’t lose anything by trying different vehicles.

While this guide is quite effective, it is not a speedrun. There are more efficient ways to complete areas 100%.

On the Mountain River map, we will discover the following elements:

  • 3 watchtowers,
  • 5 improvements,
  • 1 vehicle,
  • 16 missions (9 contracts + 5 tasks + 2 challenges),
  • 0 successes.

Step 1: Discover the map and improvements

Before you start and go to the River Mountain map, activate the contract Mountain delivery . Use the Azov (or your favorite all-terrain vehicle) equipped with the small loader crane, low hitch, and a flatbed semi-trailer. Then collect the barrels of oil and go to the Mountain River map. You will also take the Tatarin with you as there is no garage on the new map.

As usual, first explore the map fully before starting the missions. Use the Tatarin to visit the 3 watchtowers and collect the 5 upgrades , you can help you with our article devoted to the question and the map above.

Step 2: Unblock the roads in the area

Two roads are blocked on this map. To unlock them, start with the task Bridge restoration which will allow you to open the main deck. With your semi-trailer you can collect everything you need in one trip. Then make the contract Mountain pipeline construction which requires us to deliver a very large amount of things to fix the pipeline.

Step 3: Validation of contracts in the area

It is now much easier to complete contracts and tasks that remain in the zone. With your all-terrain truck equipped with the semi-trailer, complete the following contracts: Woodworking Plant Supplies , More rooms , On top of the world , Delivery to the village and Mountain maze . Also take advantage of having the trailer to complete the task Bricks in the river .

Step 4: Complete the last tasks

Leave the semi-trailer aside in an accessible place (such as the petrol station) and collect a service trailer from, for example, the service center. Use it to complete the task The beast of burden and unlock the Caterpillar 745C . Even though this vehicle looks very cool, it is ultimately not that practical, so you can pick it up at the garage. You can also use your offroad truck to make Environmental problem .

Finally, use the Tatarin to complete the two challenges in the area, From top to bottom and Challenges of the river and to complete the last task in the area Service convoy .

Before moving on to the next region, there is a trailer for delivery on the previous map, North Port. This time all the roads are paved, but I advise you to use a heavy truck in order to complete the contract. Dismantling of the drilling platform . Return to the Mountain River map with your all-terrain truck and semi-trailer. Now is the time to finish the last contract, Drilling equipment .


By this point you should have discovered 7 Watchtowers, unlocked 13 upgrades, and completed 44 Missions (16 Contracts + 22 Tasks + 6 Challenges) Congratulations, you can now head to the third map in the area, White Valley.
