Redogörelse (dagbok) för arbetena vid Kölmjärv 20/7 - 10/8 1946

This document, titled 'Redogörelse (dagbok) för arbetena vid Kölmjärv 20/7 - 10/8 1946' (Report (diary) for the work at Kölmjärv 20/7 - 10/8 1946), serves as a daily log of field operations conducted at Kölmjärv, Sweden, during the summer of 1946. The log begins on July 20, 1946, with the arrival of reconnaissance personnel and a work crew. The primary objective of the operation appears to be the systematic search of an 'impact site' (nedslagsplatsen). Over the course of the documented period, the team utilized various methods, including ground probes (jordsond) and, later, an electrical projection apparatus (el.projsökningsapparat), to survey specific areas designated as 'område 1' through 'område 4'. The work involved clearing lines, building rafts, and conducting depth soundings at the Kölmjärv outlet. The personnel strength fluctuated throughout the operation, starting with a small team and expanding to include additional workers and civilians. The log entries detail daily activities such as searching, probing, and moving equipment between designated zones, indicating a methodical and sustained recovery or investigative effort at the site.
