Bonpland is the remains of a lunar impact crater that is attached to the walled plain called Fra Mauro to the north and Parry to the east.[3] The intersection of their rims forms a three-pointed mountainous rise. To the southeast is the small crater Tolansky. Bonpland lies on the eastern edge of Mare Cognitum.[4]

Bonpland and its satellite craters

This rim of Bonpland is heavily worn and eroded, with the intrusion of Parry in the east creating a bulging extension to the southeast.[5]: 76  The floor has been flooded by lava in the past, leaving a relatively flat surface that is broken by a series of narrow clefts. These are collectively designated the Rimae Parry. The clefts cross the rim to the south and also to the north, with Rima Parry V extending into the neighboring Fra Mauro. There is a volcanic cone associated with the latter cleft.[6]

This crater is named after Aimé Bonpland (1773-1858), a French explorer and botanist.[1] His name was incorporated into lunar nomenclature by German astronomer J. H. von Mädler by 1837.[7] Its designation was officially adopted by the International Astronomical Union in 1935.[1]

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Bonpland.[8]
