  Using the EAS size spectra measured with the MAKET ANI array on Mt. Aragats,
Armenia (3200m a.s.l.) in the range of the shower size 10^5 - 10^7 for
different angles-of-incidence, the EAS attenuation length has been determined
applying different analysis methods. The analysis is based on a data sample of
2.5*10^6 events collected in the period of June, 97 - April, 99. The results
are compared with results deduced from data of the EAS TOP and KASCADE
experiments.
