Abstract : This is the initial progress report on installation of a two-directional 21-element crossed linear array, one line oriented NW-SE, pointed in the direction of the Nevada Test Site. Work was begun immediately on design and preparations for installing the array and expanding the electronic circuits in the TFSO trailer to be used as a temporary recording station. Recording of five seismometers on a Develocorder was started on 13 July. By the end of July, all eleven seismometers on the NW-SE line were being recorded on the Develocorder and most of those on the cross line were installed and calibrated. Two tape recorders were received and are being installed.
