This seed is a bit of contradiction climate wise. You spawn in ice plains and ice mountains biomes, but all around the snowy areas are savannas and even a desert.
Even with how odd it may be, this seed is still awesome because it has a mineshaft down in a ravine and a temple in the desert. Those will leave you with some great items to use when exploring the different biomes of this seed.

The Ravine and Abandoned Mineshaft
After you spawn, travel north until 30 / 64 / -141 to find the ravine. It almost acts as a border between the savanna patch and the snow.
If you look down into it, you can see the wooden planks that mark the beginning of the abandoned mineshaft. This mineshaft continues through a second ravine and onward. You can explore it to see what all you can find, including how many chest minecarts it has.
The Desert Temple
If you want more chests to loot, you can return to the surface and continue north out of the cold climates and into the desert. Around 10 / 71 / -347 you’ll find the mostly buried temple.
If you can get down to the bottom of the drop under the purple clay without setting off the pressure plate, you’ll have four more chests to loot. These chests are full of gold, iron, a saddle, and even an emerald.
These are just a couple of key features on this seed. There are plenty of caves or other areas to explore both in the cold climate areas and in the hot ones. Search around for yourself and see what else you can find!
