Photos from Cherenkov Telescope Array’s post

This month’s “Picture(s) of the Month” are from the geotechnical study underway on CTA’s southern hemisphere site in Chile. The teams will drill 39 boreholes and dig 20 strip excavations to understand the geological conditions of the site, which will be valuable input to the final foundation designs.
