Getting ready for Iceland

Part 2 of my Iceland saga begins soon. My main concern will be power and SD card management, especially since this time I am camping. One possible issue with the itinerary so far is going south west through the interior from Askja (right in the middle of the map below) since the roads may still be impassible with multiple river fords. Best bet will be to speak to the rangers at the station before beginning the hike to soak in the Viti crater. More soon.
