BRIEF DESCRIPTION
The north-western part of Mare Imbrium with the beautiful Sinus Iridium, and the Jura mountain range which forms its edge. Sinus Iridium is crossed by mare ridges. Luna 17, which landed to the south of Cape Heraclides, transported an automatic mobile laboratory, Lunokhod 1, to the Moon. Refer to your Antonin Rukl lunar atlas chart, page 47.
