The investigation of extensive air showers produced by primary cosmic rays with energies of 10¹⁴ - 10¹⁶ eV is of interest because of the "knee" feature of the primary spectrum, where there is a sharp change in the slope of the energy dependence of the cosmic ray intensity. There is a current state of confusion in the understanding of the origin of this feature and of the primary mass composition at these energies. Several major installations are exploring this energy region. These will be discussed, with particular emphasis on recent results from the GAMMA array on Mt. Aragats in Armenia.
