This is what opportunity rover was doing Sol 2171,
"sols 2166-2171, February 26 - March 03, 2010: Driving Around Material Ejected From Young Crater
Opportunity is continuing the circumnavigation of "Concepción" crater. During this period Opportunity traversed around a ray of ejecta that is
comprised of rock debris from the impact that formed the crater.
In Mars Reconnaissance Orbiter images these rocks and their shadows appear as dark streaks extending to the south and southwest from Concepción
crater. Data collected on Sols 2165 (Feb. 25, 2010) and 2166 (Feb. 26, 2010), indicated potential targets for direct measurements with the Instrument
Deployment Device (IDD). A 22-meter (72-foot) drive along the ejecta ray was performed on Sol 2167 (Feb. 27, 2010). However, because of the assessed
mobility risks associated with this part of the jumbled rock field, no in-situ targets were approached. Instead the rover continued the
circumnavigation campaign with an 18-meter (59-foot) drive around the ejecta ray on Sol 2171 (March 3, 2010).
As of Sol 2171 (March 3, 2010), the solar array energy production was 278 watt-hours with an atmospheric opacity (tau) of 0.396 and a dust factor of
0.481. Total odometry is 19,399.57 meters (12 miles)."
I guess 'circumnavigation' is the operative term for that period.
