Small snowboarder triggered avalanche near rocky features on BC glacier. Couple of meter sized slabs started moving after a fall by snowboarder, luckily only traveled for a few meters and no one got buried. There appears to be a very big variety in snowpack even inbounds. Higher up in the glacier seemed more unstable than lower down even though snowpack was relatively similar throughout. Avoid steep and rocky terrain as snow appears looser around those areas
