This georoute follows the Flamisell River, backbone of the Vall Fosca, from Pobla de Segur to Sallente.<\/p>\n
From south to north, the route plunges into an area with geology that will transport you back in time. The colours speak for themselves. Greyish tones are limestone, representing former reefs. Reddish tones are conglomerates that represent the formation of the Pyrenees and the silt and sand deposited by rivers that carved through the region 250 million years ago. Whitish tones are granite, created by cooling magma. The darker colours represent the oldest rocks in the Geopark, 500-million-year-old sandstone and slate that are frequently used in the construction of roofs for houses, barns and churches.<\/p>\n
The residents of the valley have exploited this rich geodiversity with different mines, such as the Castell mines. The head of the valley is also home to the first great hydroelectric power plant in Catalonia, built at the beginning of the 20th<\/sup> century. This exploitation of natural resources played an important role in the history of the Vall Fosca.<\/p>\n","protected":false},"excerpt":{"rendered":" The force of water converted into energy: this area is home to Catalonia\u2019s first hydroelectric power plant, as well as former mines, rocks dating back more than 500 million years and granite formed from magma.<\/p>\n","protected":false},"featured_media":30814,"template":"","meta":{"_acf_changed":false,"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":""},"categoria-georutes":[428],"tag-georuta":[461,504],"class_list":["post-34343","georutes","type-georutes","status-publish","has-post-thumbnail","hentry","categoria-georutes-georuta-vall-fosca-en","tag-georuta-en-cotxe-en","tag-georuta-by-car"],"acf":[],"taxonomy_info":{"categoria-georutes":[{"value":428,"label":"Georute: Vall Fosca, energy valley"}],"tag-georuta":[{"value":461,"label":"By car"},{"value":504,"label":"by car"}]},"featured_image_src_large":["https:\/\/www.geoparcorigens.cat\/wp-content\/uploads\/Vall-FoscaJCM_6018_R-1024x331.jpg",1024,331,true],"author_info":[],"comment_info":"","_links":{"self":[{"href":"https:\/\/www.geoparcorigens.cat\/en\/wp-json\/wp\/v2\/georutes\/34343","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.geoparcorigens.cat\/en\/wp-json\/wp\/v2\/georutes"}],"about":[{"href":"https:\/\/www.geoparcorigens.cat\/en\/wp-json\/wp\/v2\/types\/georutes"}],"version-history":[{"count":0,"href":"https:\/\/www.geoparcorigens.cat\/en\/wp-json\/wp\/v2\/georutes\/34343\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.geoparcorigens.cat\/en\/wp-json\/wp\/v2\/media\/30814"}],"wp:attachment":[{"href":"https:\/\/www.geoparcorigens.cat\/en\/wp-json\/wp\/v2\/media?parent=34343"}],"wp:term":[{"taxonomy":"categoria-georutes","embeddable":true,"href":"https:\/\/www.geoparcorigens.cat\/en\/wp-json\/wp\/v2\/categoria-georutes?post=34343"},{"taxonomy":"tag-georuta","embeddable":true,"href":"https:\/\/www.geoparcorigens.cat\/en\/wp-json\/wp\/v2\/tag-georuta?post=34343"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
