Field photos from January 2016 from along the master fault within the LOFZ in and around the Huemules Cirque (HC). (A) Oblique helicopter photo looking south toward Exploradores Bay and Laguna San Rafael from the HC. Main fault trace is the low forested valley. Note the young lahar plain from the Hudson Volcano. (B) Oblique helicopter photo looking north along the LOFZ over the HC. Red arrows show two lineaments consistent with displacements observed (shown in Fig. 5), and sag ponds. Note the widening of the main HC valley to the North versus the narrow valley with the Huemules Creek draining south. Orientation of photo C shown in panel. (C) Oblique Helicopter photo looking West (position shown in (B)), showing the two main lineaments along the master LOFZ and sag ponds. Note how the valley widens on the right of the photo as per the width of the main glacial valley that is being translated northwards by long term dextral slip along the LOFZ (i.e. the HC is being beheaded over time due to northwards dextral motion along the LOFZ). (D) Field photograph looking North along the LOFZ at the sag pond shown in (C). This low-lying (along strike) linear pond is consistent with the main damage zone of the master fault here. Star is located above a machete with flagging tape attached stuck in the ground for scale (~ 40 cm is above ground in photo). Field and Helicopter Photographs by G.P. De Pascale.
