Just woke up.
Teams arrived in Calama at 8:50am if theri flight was on time. They then went North to the mine, did the detour went back towards Calama (or around the outskirts), drove southeast to the Valley of the Moon then turned back towards Clama and slightly north to the Valley of teh Dead.
Kevin and Drew said they were driving for about 4 hours in the clips from the finnish line, so I expect the teams took about 3 to 3 and a half hours driving after the mine detour.
So I think the arrival times will be 12:40pm to 1:40 pm. Without knowing how long the task took (including safety talk, changing into gears, getting out of the airport, ect)
But that is just a very, very rough guess. Where's Chateau and shadows, we want sahdows.
