Ridiculousness and plot holes galore

I'm just going to nitpick about some of the retarded things in this film. That said it was fairly entertaining and I don't regret watching it.

I'm curious how the old man had GPS coordinates marking where he hid the gold when he went to prison before GPS was available? MAYBE he could've marked latitude and longitude from a topo map for section of the area it was in, but not an exact set of coordinates.

How did a night of exposure to Will's socked and booted foot cause severe when the other people didn't have gloves or hats and only started having mild frostbite. Their fingers, noses, ears were exposed for two days and a night!!!

If it was so cold how did they dig up dirt with sticks, rocks and a crowbar, when permafrost would've made digging that box out impossible? I won't get into the ever fluid mobility of the chain that was buried 20 years. Also, how the *beep* were they dragging an ice cold chain with their already frozen, mildly frostbitten bare hands? I could chalk it up to greed, but I highly doubt Cheryl could've been doing that considering she was minutes away from dying of exposure.

Why would Cheryl poison a bottle of liquor in a bathroom? Literally how could she guess the trapper would consume it before heading off to find $20,000? She had no worries about him coming based off of a random assumption. To that note, if that was the trappers liquor of choice, I'm fairly positive he would've noticed the distinct taste of rat poison. Also, a poor man technically evicted didnt immediately head off at the prospect of $20k knowing there are four people in the woods that know about the money? No he decides to chill and drink his poisoned liquor.

Lastly, Will was in possession of stolen items including a gun. How was he not under arrest and under watch of the police? The officer talks to him and then leaves him!!

Just stupid *beep* that irked me.
