| Remarks | 1. Puurauk, mida on kirjeldanud H.Viiding (päevik 14, 1967) Värska 6 nime all, on tegelikult Värska 1 pa. Segadus tekkis ilmselt puuraukude Värska VI ja SG 6 numbrite segamini ajamisest. 2. Värska 6 puuraugu ID ei saa olla 971, nagu näidatud puursüdamiku kastide juures. Puurauk ID-ga 971 on 463 m sügav, see siin aga 595+m 3. Ulatub 6 m vundamenti. Puuritud Gdovi kihtidest soolase vee saamiseks, vesi surveline, deebit ~14l/sek |
