In sailing, a joke exists that there are three types of sailors. Those who’ve grounded, those who are lying, and those who will soon. Much the same exists for driving offroad and getting stuck.
If you drive graded dirt all the time or limit yourself to mall crawling, “recovery” can seem like a worst case scenario. But at least for me in the 16/17 winter up here in the Sierras I’ve pulled three vehicles free, shoveled out half a dozen, and high centered myself thrice (counting today). I have a winch, strong attachment points, big ass shackles, a real no-shit shovel, two recovery straps, some chains, and traction pads. None of that keeps you from getting stuck but it will give you a fighting chance to get out of it.
Things get snow-stuck in all kinds of ways, but usually the most pain-in-the-ass is the high center. Simply put, you compact so much snow underneath the bottom of the vehicle that you create (via the pressure of your axles/difs/undercarriage/etc) a solid block of ice that is supporting all the vehicle’s weight.
This of course is a problem because if the cool new made-of-compacted-snow jack stands under your truck are holding you up guess what isn’t? That’s right, your tires. So your tires sit there spinning happily in the air, laughing at you and all your locking differential technology. In fact, the more the tires spin, the deeper they make their little holes, compressing the snow further and further under the vehicle. It sucks.
When high centered, your options are limited. You can attempt to shovel out the snow which is fully caked under your vehicle, but remember it is highly compressed to the point that you are nearly going at ice blocks. Plus, you’re coming at it from the sides and will have a hell of a time getting an angle. I’ve only seen this work when one axle is stuck. If both are, which means the entire undercarriage is, read on.
You can use a winch or a buddy’s truck with a strap, but basically you’ll need to drag the vehicle where it’s got to go. As a bonus you can toss some traction pads under the tires (the orange things strapped to my spare tire in the picture above). An upshot with snow is that for the most part it’s fairly slick so once you get out of the augered holes that your tires have made, you should be able to move.
The third mechanism falls into road-building albeit no dynamite required. If you have a hi-lift jack (and bumpers/sliders you can attach to) then you can lift the vehicle up and off it’s high centered mess, jamming rocks/dirt under the tires to make a solid track for the wheels to travel on. Likewise, you can shovel out the part in the middle (ahead of the vehicle) where you would get high centered again. This is grueling multi-hour work to even make it 100′, depending on the snow conditions.
If you’re dangerous, stupid, and lucky, you could always try using a blow torch to melt the snow. Make sure you film this so if you ignite the gas tank the video can go on youtube and make a lot of money for your family.
Obviously the easiest thing is simply to avoid the problem in the first place. If the snow is more than a foot thick (or taller than the bottom of your axles), don’t go into it. Remember that snow cats exist for a reason; wheeled vehicles can only do so much in snow.
Additionally, be careful about driving around early morning. The snow is harder then so you’ll float a little better. The same route when tried a few hours later could prove impassible. In the first picture above, way in the background there’s a subaru; it’s not going anywhere for weeks. I’m assuming it got out there on a cold icy night, and is now surrounded by soft spring snow.
For more information, feel free to read up from folks who’ve done this much more often than I have: it’s not like there’s one way to get stuck or unstuck. Open your mind, brother.
