Tests were conducted at Fort Churchill (Canada) to determine if critical depth curve obtained earlier for small charges could be extrapolated for larger charges; results, based on firings of 3 100-lb and 4 500-lb charges of Atlas 60% gelatin dynamite, indicate that definition for critical depth must be revised for larger charges.
