SHORT HISTORY
The USGS ,nd C. LT. cooperate in funding ,nd operation of the above-mentioned stations. C. LT. also maintains another large
network in this area. The responsibiIi ty for the different networks- occasionally shifts between C.LT. .nd C.I.T.-USGS.
Tht"st" statIons ore grouped lnto lIve networks; MOJave, ImpenaI Valley, Carrizo Plain Palmdale, Do, Cuadros, ,nd Santa
Barbara-Pt. Mugu.
Moj ave network comprises (BC2) , CMH, CO2, (CPM) , EAG, (GRP) , (HUG) , (INS) , (IRN), (LEO), (LTC), LTH, (PNM) , (RMR), (ROD),
(RVH) , RVS, (Sllli) , SPM, TTM, .nd WH2.
Imperial Valley network i, composed of AMS, (BON), (CLI), COA, (COR) , COT, CRR, (ELR) , (FNR) , lNG, (IIWR) , OBB! PLT! RUN I SGL,
SNR, (SOP), (wIS), wLR, (wML) , and (F 1M) Arlzona, (LGA) Arizona. (SLU) Arizona, .nd (YMD) Arizona.
Carrizo Plain-Palmdale network consists of (ABL) , (BCH) , (BMT) , (CRG) , FTC, (LHU) , (PKM) , (RYS) , (TMB), .nd (YEG) .
Santa Barbara-Pt. Mugu network comprises AIC, BCC, BCD, BLG, ELP, BSC, BSM, BSN, (CAM) , (ECF) , (KYP) , LPe, (PTD). (SAD) , .nd
(SIP) .
FTC began operation in November 1952. This station ron until it .., closed in the 1960's. The present location i. nearly
identical to that of the old station.
C. I. T . • nd the USGS publish frequent reports on the data collected through their several networks.
