There is plenty of additional information of the Murtèl rock glacier:

\n\n\n\n

Deformation of the borehole 1987 – 1994 (S. Wagner, M. Hoelle, D. Vonder Mühll)

\n\n\n\n

Geophysical surveys: Refraction seismics, DC resistivity sounding, DC resistivity mapping, DC resistivity tomography, ground penetrating radar (GPR), gravimetry, EM-31, BTS (D. Vonder Mühll)

\n\n\n\n

Photogrammetry (A. Kääb)

\n\n\n\n

Rock wall investigation (N. Matsuoka)

\n\n\n\n

In spring 2000, there will be two additional borehole drilled, some 20 and 40m upwards. Main goal is to take frozen cores. However, deformation (qualitatively) and temperature will be determined as well as hydraulic tracer experiments will be conducted. (D. Vonder Mühll, S. Springman)
