Until now the only topography they've encountered has been what the sheet of frozen water has afforded them but now they've got the land mass to deal with. Fortunately for us, we've got Google Earth and the many modern-day resources available which allow us to join their endeavor from our cozy armchairs.
Offroading Home has developed an extensive Google Earth Resource File which brings all the meaningful resources together in one place and it's available free: Scott Expedition: Antarctica
Today we've updated it extensively and we should probably describe the new features:
NASA's MODIS satellite images is one of the overlays available merely by clicking the box next to the "MODIS Ice Overlay" link in the "places" legend on the left hand side of the screen. These extensive images are completely updated every three days to display the earth's resources – in this case, the earths ice coverage.
It does take some getting used to, and it's better for some places (like flat ice) than others (like mountainous areas) but they're so good you can follow as the explorers wind their way between the undulations in the ice caused by glacier flow.
One note though. As with most maps, sectors near the poles get "scrunched" so while a normal viewing screen at the beginning may contain only 4 or 8 sectors, a similar viewing screen at the poles could contain upwards of 50 or so. That translates into some increased downloading time for the images – just be patient, it's worth the wait for the added detail.
Webcams are maintained at both the McMurdo and South Pole stations (weather permitting) and the resource file contains pop-up links to both of them. The two cams as McMurdo seem to have been working for the duration of the trip. The two at the Pole Station, however, are dependent on satellite passes so come and go at regular schedules.
The Historic Expeditions of Scott, Amundsen and Shackelton have been added to the trails list. Click their boxes and you can see how this current expedition's route compares with what the earlier explorers did.
Grid Lines were added when the two isolated explorers seemed to need some intermediate goals in order to not let the daunting task overwhelm them. Commenters on their blog could then congratulate them each time they crossed one of the decimal degrees in latitude – and there have been six of them (coming up on the seventh).
View placemarks (tiny purple cameras) are new to this update and enable you to change your Google Earth views quickly in order to take advantage of the 3D topography.
We hope you are enjoying following along this "reality show" with us. It's not often we get a chance to do this without needing to trailer to a trailhead.
