Segue-se um po\u00e7o de 12m\u00a0com a base coberta de calhaus de v\u00e1rias dimens\u00f5es e muita argila. No sentido NO h\u00e1 um pequeno recanto com diversas formas de reconstru\u00e7\u00e3o muito bonitas e de boas dimens\u00f5es. A\u00ed\u00a0existe tamb\u00e9m um pequeno po\u00e7o com 5 metros de profundidade muito estreito e identificado na topografia. J\u00e1 no sentido N, encontra-se um po\u00e7o com 11m, pelo qual se chega a nova sala, com blocos de v\u00e1rias dimens\u00f5es e muita cascalheira e argila. A sala, se assim lhe podemos chamar,\u00a0tem tendencialmente inclina\u00e7\u00e3o para E, e no recanto mais a NO h\u00e1 um pequeno tramo com formas de reconstru\u00e7\u00e3o muito bonitas.\u00a0\u00a0O algar continua a desenvolver-se, encontrando-se uma passagem sensivelmente a meio da sala por debaixo de um grande bloco. A passagem d\u00e1 acesso a uma rampa de muita argila com aproximadamente 4m, ai chegamos a um po\u00e7o de 15m. Descendo esse\u00a0po\u00e7o nota-se as paredes de calcite e uma boa abertura no sentido NNE, e\u00a0no sentido contr\u00e1rio encontra-se um po\u00e7o paralelo.\u00a0Na base do po\u00e7o seguindo para NNE, h\u00e1 uma zona com muitas formas de reconstru\u00e7\u00e3o parietais.\u00a0Aqui, ap\u00f3s passarmos por pequeno obst\u00e1culo, entramos numa sala de boas dimens\u00f5es no sentido N\u00a0repleta de grandes blocos e muita cascalheira, com inclina\u00e7\u00e3o no sentido N e\u00a0tecto\u00a0alto e irregular. No final da sala, na zona mais a Norte, h\u00e1 uma pequena abertura de onde se deslumbra um oco identificado na topografia como possibilidade de continua\u00e7\u00e3o.\u00a0Regressando \u00e0\u00a0base do po\u00e7o de 15m, agora no sentido S, acedemos a novo po\u00e7o de 7m com\u00a0a sua base repleta de calhaus.

J\u00e1 no sentido S h\u00e1 um novo po\u00e7o, tendo este 11m. Podemos dizer at\u00e9 que estes 2 po\u00e7os s\u00e3o o mesmo com um patamar a dividi-lo. A base est\u00e1 repleta de argila com algumas pedras, notando-se a acumula\u00e7\u00e3o de \u00e1gua.\u00a0<strong>Geologia:<br \/><\/strong>A gruta aparenta ter um controlo estrutural por fam\u00edlias de fraturas de atitude NW-SE\/subvertical e NE-SW\/subvertical. As camadas regionalmente t\u00eam dire\u00e7\u00e3o aproximada NW-SE e inclina\u00e7\u00e3o suave para Sul, embora localmente possam ser consideradas subhorizontais. \u00a0A gruta desenvolve-se em calc\u00e1rios da forma\u00e7\u00e3o de Calc\u00e1rios Biocl\u00e1sticos do Coda\u00e7al, datada do Batoniano, do Jur\u00e1ssico M\u00e9dio.

Descendo uma rampa com v\u00e1rios ressaltos no sentido SE\u00a0chegamos a uma sala de fundo irregular com grandes blocos, cascalheira e argila, aqui e ali com pequenos dep\u00f3sitos de \u00e1gua. O tecto de aspeto irregular com um grande bloco ali suspenso\u00a0aparenta ser uma fratura, se assim lhe podemos chamar. Continua-se a progress\u00e3o numa pequena passagem a NNE\u00a0nesta sala atr\u00e1s de um grande bloco, seguindo agora no sentido ESE, e ap\u00f3s pequeno destrepe chegamos a uma zona de meandro.<br \/>\nInicialmente rastejando verifica-se que a NO\u00a0o meandro est\u00e1 completamente fechado, continuando no sentido ESE. \u00c0\u00a0medida que se avan\u00e7a o tecto sobe permitindo andar de p\u00e9. Aqui o ch\u00e3o est\u00e1\u00a0todo coberto de argila, algumas formas de reconstru\u00e7\u00e3o, poucas em pequenos recantos. Notam-se v\u00e1rias marcas de linhas de \u00e1gua feitas pelas cinzas que se infiltram com a \u00e1gua de inc\u00eandios passados, depositadas nas paredes mais junto ao tecto.<br \/>\nAp\u00f3s avan\u00e7armos cerca de 62m\u00a0chegamos a uma zona de rolh\u00e3o, com algumas formas de reconstru\u00e7\u00e3o no inicio e afunilamento da zona. A\u00ed, ap\u00f3s se avan\u00e7ar cerca de 11m em zona desobstru\u00edda, encontramos um pequeno dep\u00f3sito de \u00e1gua originado devido\u00a0a um pequeno desn\u00edvel.<br \/>\n<strong>Geologia:<\/strong>O po\u00e7o de entrada do algar pode ser considerado como um vadose shaft, segundo a defini\u00e7\u00e3o de Baron 2003, ou um algar de infiltra\u00e7\u00e3o, numa tradu\u00e7\u00e3o n\u00e3o literal do termo.<br \/>\nA galeria\u00a0que se atinge no fundo do po\u00e7o de entrada apresenta evid\u00eancias de ter tido origem na zona fre\u00e1tica, de acordo com a defini\u00e7\u00e3o de Bogli, 1980. A galeria apresenta a mesma dire\u00e7\u00e3o\u00a0NW-SE\u00a0que as camadas a n\u00edvel regional. A gruta desenvolve-se em calc\u00e1rios da forma\u00e7\u00e3o de Calc\u00e1rios Biocl\u00e1sticos do Coda\u00e7al, datada do Batoniano, do Jur\u00e1ssico M\u00e9dio.<br \/>\nA galeria representa a posi\u00e7\u00e3o de um antigo n\u00edvel de \u00e1gua cuja cota ronda atualmente os 410-420 metros. Ap\u00f3s a sua forma\u00e7\u00e3o, uma subida do n\u00edvel de base\u00a0ou outro fen\u00f3meno que tenha diminu\u00eddo a velocidade de circula\u00e7\u00e3o da \u00e1gua\u00a0ter\u00e1 provocado o seu preenchimento com os sedimentos detr\u00edticos, que ainda hoje preenchem parcialmente a gruta. Posteriomente uma descida relativa do n\u00edvel de base ter\u00e1 provocado a passagem da gruta da zona fre\u00e1tica para a zona vadosa inativa.<br \/>\n<strong>Presente:<\/strong>Foi um prazer enorme reviver ali naquele rolh\u00e3o, os grandes momentos que ali se passaram na altura do inicio da desobstru\u00e7\u00e3o com esse grande grupo que \u00e9 o C.E.A.E.-LPN.\u00a0Foi ali que o meu grande gosto pela espeleologia foi cimentado, at\u00e9 a roupa interior tinha argila. \u00c0\u00a0sa\u00edda apanh\u00e1vamos amoras para o grande Pedro Frade fazer as deliciosas tartes de amora.\u00a0Se assim me for permitido ainda levarei fornadas de espele\u00f3logos a abrir mais um pouco, para que ganhem o \"bichinho\" que aqui nos faz
