The experimental results obtained at the Baksan underground scintillat
ion telescope are briefly reviewed. The neutrino Aux from galactic sou
rces has been studied, and an upper limit. has been obtained on it. An
upper limit has been placed on the flux of heavy magnetic monopoles b
y searching for slow ionizing particles. The signal from the neutrino
momentum in supernova birth has been detected, A limit on proton decay
has been obtained. By recording muons from extensive air showers, it
has been shown that their chemical composition does not vary up to 5 x
10(15) eV. (C) 1998 American Institute of Physics.
