Short summary
We propose an alternative electrode to perform Electrical Resistivity Tomography measurements in coarse blocky environments, such as rock glaciers. Compared to the traditional steel spike electrodes, which need to be hammered between the blocks, the proposed steel-net electrodes can be easily pushed between the builders by hand and then removed. Furthermore, the steel-net electrode weighs one-sixth of the steel spike, and is, therefore, easier to carry in challenging mountain environments.
