Geocache Description:

Why do we have tunnels?
Pedra Branca - ER101 - Ribeira Funda

Esta cache irá te convidar a conhecer parte da Estrada Regional 101
A Estrada Regional (ER) número 101 (ER101), com 205 km de extensão, merece especial destaque por ser uma obra de engenharia notável, realizada com os meios limitados da época, que só encontra paralelo na extraordinária rede de levadas construída ao longo dos séculos. Foi concluída a 6 de junho de 1958, com a inauguração do túnel Boa Ventura/Arco de São Jorge. Na passagem para o séc. XXI, encontra-se sem circulação rodoviária principal, mas está ainda na lembrança de muitos madeirenses e turistas o percurso vertiginoso da estrada escarpada na rocha da costa norte, desde São Vicente ao Porto Moniz. A sua imagem ficou gravada em muitos postais madeirenses.

Ao longo dos 3km (ida e volta) irás conhecer os problemas e ao mesmo a beleza desta outrora importante estrada. 
Este percurso deverá ser feito com boas condições metereológicas. Evita os dias de chuva e vento.
No início o percurso é acessível, tendo apenas uma área mais sensível após o túnel de acesso à Ribeira Funda.
A resposta à Stage 1 te dará as coordenadas finais.

Quantos buracos há no pequeno muro em frente à àgua? 
3 = N 32° 49.891' W 17° 7.866'
5 = N 32° 49.910' W 17° 7.917'
7 = N 32° 49.939' W 17° 7.984'

Boa sorte!

This cache will invite you to visit the Regional Road 101.

The Regional Road (ER) number 101 (ER101), with 205 km of extension, deserves special mention because it is a remarkable engineering work carried out with the limited means of the time, that only finds parallel in the extraordinary network of "levadas" constructed along the centuries. It was completed on June 6, 1958, with the inauguration of the Boa Ventura / Arco de São Jorge tunnel. In the early XXI century, it longer has main road traffic, but it is still in the memory of many Madeirans and tourists the dizzying route of the steep road on the rock of the north coast, from São Vicente to Porto Moniz. Its image was engraved on many Madeiran postcards.

Along the 3km (round trip) you will discover the problems and at the same time the beauty of this once important road.
This course should be done with good weather conditions. Avoid the rainy and windy days.
At the beginning the route is accessible, having only a more sensitive area after the access tunnel to Ribeira Funda.
The answer to Stage 1 will give you the final coordinates.

How many holes are there in the small wall in front of the water?
3 = N 32° 49.891' W 17° 7.866'
5 = N 32° 49.910' W 17° 7.917'
7 = N 32° 49.939' W 17° 7.984'

Good Luck!
