Bringing this forward because I found a list of the areas searched in addition to around Pico Salvaguardia, the Venasque refuge & originally planned route.
It’s from the Spanish news outlet La Vanguardia’s 4/12 edition

“After a week of intense search, yesterday, an operation made up of specialists from the mountain rescue and intervention groups of the Civil Guard of Benasque, Boltaña, Huesca and Jaca, as well as the Huesca Air Unit, again scanned extensive areas of the Pyrenees trying to find a trace of the woman without success. The teams covered different areas: the Salenques crest, the Coronas refuge, the Literola valley, the Perdiguero peak and the Estós valley, reported the Huesca commandant. Troops based in Vielha, as well as the Val d'Aran firefighters, also joined in to search the Catalan side. Nor is it ruled out that she changed her initial plans and followed another itinerary.”
“
Tras una semana de intensa búsqueda, ayer, un operativo integrado por especialistas de los grupos de rescate e intervención en montaña de la Guardia Civil de Benasque, Boltaña, Huesca y Jaca, además de además de la Unidad Aérea de Huesca, volvieron a rastrear amplias zonas del Pirineo intentando dar sin éxito con algún rastro de la mujer. Los equipos se repartieron por distintas áreas: la cresta de Salenques, el refugio Coronas, el valle de Literola, el pico Perdiguero y el valle de Estós, informaron en la Comandacia de Huesca. También se sumaron efectivos con base en Vielha, así como de los bomberos de la Val d’Aran, para explorar la parte catalana. Tampoco se descarta que cambiara sus planes iniciales y siguiera otro itinerario.”
I’ve included the original Spanish quote because my Spanish isn’t great & my translation is aided by Google (which I don’t always trust).
I’ve been having a look at some of the terrain on maps & photos and sadly I can see plenty of places for an accident to occur and for a body not to be easily found.
