This was roughly 26 miles (40 km) away, across the edge of the Allardyce Range. Another whaling station was known to be at Prince Olav Harbour, just six miles (10 km) north of Peggotty Camp over easier terrain, but as far as the party was aware, this was only inhabited during the summer months. Shackleton and his men did not know that during their two-year absence in Antarctica, the station's owners had begun year-round operations.[88]
