Neutron monitor counts observed at Climax have been used to study galactic cosmic ray modulation during the time interval 1953--2001. This interval covers five solar cycles including four-field reversal. Cosmic ray intensity (CRI) is better correlated (r = 0.93) to the solar coronal hole area (CHA) than to solar activity represent by the sunspot number (R). The heliospheric current sheet (HCS) tilt angle, Ψ, tracks CRI very well by several solar rotations a head. CRI is anticorrelated to the magnitude of the interplanetary magnetic field (B) as well as to the product of B and solar wind speed (BV). It lags CHA by 3--6 solar rotaion during A 0. CRI lags B by 4 solar rotations and the product BV by 2 solar rotations during A 0.
