Foto NASA JPL Opport'yuniti izmenenie sleda v techenie vos'mi let proishodilo postoyanno. Obratim vnimanie, na fotografii prisutstvuet yavnaya anomaliya komok peska vyshe razvoroshennogo mesta ne izmenilsya. Togda kak v sluchae vetrovoi versii etot komok naibolee podverzhen erozii.
Dlya prosmotra izmenenii neobhodimo otkryt' gif.

Takzhe paradoksal'no to, chto sled zarastaet ravnomerno, togda, kak cherez kazhdyi metr sled ne pridavlen i dolzhen byt' vynesen po vetru. No sled vyravnivaetsya, tak kak esli by byl ukatan absolyutno rovno. Soglasimsya v sluchae analogii zemnogo peska lezhashego poverh tverdoi poverhnosti veter nepremenno ogolil nekotorye mesta.

Vosem' let postoyannogo zarastaniya sleda rovera ostavlennogo na tysyachah dyun, dokazyvaet effekt opredelenno imeet mesto.
No razglazhivanie peska otsutstvuet v sluchae pereneseniya peska na nekotoroe rasstoyanie.
Pri etih usloviyah - perepad temperatury i solnechnyi veter, sohranyayutsya v tom zhe vide. Sledovatel'no, otsutstvie razglazhivaniya vynesennogo peska dokazyvaet ne prichastnost': vetra, perepada temperatur, solnechnogo vetra kak postoyannogo i neizmenno deistvuyushego faktora.
Neobhodimo naiti otvet na drugoi vopros.
- Pochemu ne razglazhivaetsya pesok, otdelennyi ot mesta nahozhdeniya na nekotoroe rasstoyanie. Primerno na 10 - 15 sm i dalee.
