b'PeopleNewsshown, in encouraging experiments, that depths as great as 10 000 feet (~3 km Ed.) may be reached without too many difficulties. Without much imagination, we may anticipate developments within the next few years to show remarkable new methods. All topographic mapping, as well as magnetic and electrical surveys, will be carried out from the air. For detail surveys, the helicopter-borne magnetometer and electrical equipment may render as much detail information as any ground survey. Regional studies employing radioactive and geochemical methods may cover very large areas in surprisingly short time.The habit of drawing maps that show two dimensions only will be succeeded by new stereoscopic projections so that the geophysical results will be seen in three dimensions, either on a screen or by using polarized light and specially prepared maps. Such maps will show, besides the topography, the position Bell 47B2 helicopter showing the magnetometer attached to the front of the bubble.
