Results obtained from a high-altiitude balloon flight from Thompson, Canada, in August, 1973, are reported. The instrument consisted of a spark chamber, a lucite Cherenkov counter, and thirteen layers of scintillators. For heavy particles the Cherenkov-range method of analysis was used to determine the mass of particles energetic enough to produce a Cherenkov signal and then stop in the layered scintillators. The data appear to be consistent with current cosmic-ray propagation models. By use of a simple exponential path length propagation model, these data are extrapolated to the cosmic-ray source, and some implications of the data are discussed as to the nature of the source.
