Key features of backcountry snow shovels:
- Material: Because of its low weight and high strength, aluminum predominates. Plastic shovels aren't suited to avalanche rescue.
 - Comfort: Low weight and a comfortable, ergonomic grip will make a shovel easier to use. 
 - Length: Longer, extended shafts may give you better leverage to scoop snow faster while shorter shafts cut down on weight.
 
Types of snow shovels:
- Fully flat blades are best for snow study, such as creating smooth snow-pit walls.
 - Scooped blades are less likely to spill snow off the sides during shoveling.
 - Serrated blade edges can be used to bust up ice.
 - Blades with holes in them can be used (with a length of accessory cord) to build snow anchors; holes also make a shovel slightly lighter to carry.
 
T-grip vs. D-grip handles:
- T-grip: Grasped between the fingers, this is a lightweight design that works well; can be awkward when wearing mittens.
 - D-grip: Slightly bulkier and heavier than a T-grip, it is relatively easy to use while wearing mittens.
