Eos Planet Map (West Part) for Mass Effect Andromeda

The western part of the planet Eos is not available at the beginning of the game due to high radiation.

After launching the Remnant Vault on Eos, the radiation starts to slow down. Do not try to visit these locations too early. After visiting Havarl and Voeld the situation will improve, but the best time to visit Eos West will be a moment after you visit the planet Kadara.
