Review

The paper presents an outdoor ephemeral art installation situated at the intersection of land art and the discipline of geology.While not a research paper in a narrow sense, the paper outlines the rationale for the artwork, presents its science as well as arts context, describes its methodology and set-up, the installation process and results in the form of lasting documentations as well as audience reception.In my view, the title in its current form captures this overall scope well and should not be changed to include one of the sub-points mentioned above.
