The glades are awesome.  Usually the best powder on the mountain can be found there.  And you can hit run after run through them.  Glades by nature are more windblown than trees or runs where snow drifts in all fluffy like, but not so hammered by wind like knobs, peaks, and bald faces can be.

So being powder snow we have the depth dimension added, so you are turning right and left (heelside and toeside), but the board or edge can also be sitting on top, down in, or down deep in the snow while riding.  How far in debends on many factors like rider weight, board dimensions, speed of travel, g-forces, etc...  One special thing that can amplify or override these factors is rider dynamic activity, mainly flexing/extending (squatting/lengthening) of the lower body.

A good way to ride glades is quicker turns (to go around the trees and stay in the fall line) while extending out into each turn, building pressure on the board, riding up the compressed snow so the board surfaces, change edges and extend into the next turn.  It takes rhythm and flow, but once you get the hang of it it is a real joy 

Glades are just riding in the trees.  Its a blast!  Where I ride at Jay Peak in VT they are famous for their glades.  I know other East Coast resorts have them too...
