Rimae Hippalus

[astroavani]

Concentric rilles are the largest and most impressive on the moon many times. The best example is Rimae Hippalus forming an arc around the eastern side of Mare Humorum . Northeast and above Hippalus a strange thing happens - some rilles bow and tornan is concave to the east . The most notable of these features is named Rima Agatharchides , but is actually a part of Rille or Hippalus family?
Rima , Rimae ( Channel ) or for some selenogistas Rille ( narrow valley ) - Fissure or channel
lava that collapsed totally or partially.
The Rimae (plural rhyme ) Hippalus are straight or curved rilles , or failure caused by tension in the crust . Other sinuous rilles are believed to have formed by fast moving lava flow . Sinuous rilles often originate crumbling volcanic vents and ramps .
In the attached picture you can see perfectly Rimae Hippalus  and Rima Agatharchides outstanding examples of the above .
A bonus that I liked very much in this photo, it was the ease of realizing that the Marth crater, actually a concentric crater, observe it carefully in the lower right corner.

My guess would be that the main one is not. R.Hippalus seem to stop at the boundaries of N & P. The fainter members of  R.Agatharchides look as if they might be continuations (partially covered by the formation of Agatharchides P, but the most obvious one is definitely in a different direction. Maybe the R.Agatharchides features formed at different times and just happened to be in the same place? Just my guess ... I just don't know enough about the formation of lunar features ...

Brilliant shot as usual...I wish I needed to copyright mine!

Superb, what more can I say?

Detalhe incrível.

Meu palpite seria que o principal não é. R.Hippalus parece parar nos limites de N e P. Os membros mais fracos de R.Agatharchides parecem ser continuações (parcialmente cobertos pela formação de Agatharchides P, mas o mais óbvio é definitivamente em uma direção diferente. Talvez as características do R.Agatharchides tenham se formado em épocas diferentes e por acaso estivessem no mesmo lugar ... Apenas meu palpite ... Eu não sei o suficiente sobre a formação de feições lunares ...

But it's a great guess! In fact this analysis was made by the great Chuck Woods in a photo of the same lineup I posted on LPOD.

A view of many features! It really is most special.

Stunning as always and another interesting and informative write up. Thank you Avani.

Superbly captured Avani, thank you for the in depth explanation.

Not often you see rills and rimae in that details. Nice.
