Portland Caves (1920x1080p50)

[@trevorfox5703]

Great video. I haven't been in these caves at the Grove since the 1980s, with what was the Youth Activities Centre!

[@joeb6410]

Great video, found them today, hopefully take a trip inside soon!

[@helentrove620]

Pheyoo, I was so relieved for you when you finally got out, you're both very brave! I love Portland and exploring but I think I'll pass on these caves hehe.

Excellent video. Thank you Nigel. Just past the exit, on the rock with the dead bird, you comment on the grooves in the rock. My guess is they are bore holes in which dynamite was rammed to blow the rocks apart as part of a querying operation.

[@Nigel_Broatch]

Yes maybe they are, I hadn't thought of that.

Tim Rose has a website with all the caves of Portland listed. I'll post a link...

[@Nigel_Broatch]

Excellent, I'll be in the area in the summer.

31:48 could be a fossilized sea bed at one point

[@boilersuitguy4980]

31:48 is concrete it was pored down there ages ago to try and seal it up

[@sadesurbex2816]

@@boilersuitguy4980 Huh, well it clearly didn't do a good job!

[@datatwo7405]

Ammonite Titanites giganteus Jurassic Portland, Dorset, UK

[@ianspaintpot]

the first one is called alotment dig the tracks were put in by cavers so they could remove the silt ect trying to find the continuation but instead they only came out in the cliff unber the alotment now known as coffin hole

[@Nigel_Broatch]

Excellent, now we know.

[@IanGrodyRules]

Pirates. They used to hide their loot there.

Hay nigel try to get your hands on a book from wessex cave club called the caves of the isle of portland it has all the surveys of all the caves it is la cave map. I think tophill library can get it but i am going back about 6 years it was published in 1996 it might be like chickens teeth now though. I think i have the surveys from nigel graham if you cannot find a copy i could try and find them if you want

[@Nigel_Broatch]

Thank you, I've made a note of that. I live 150 miles from Portland but usually in the area at least once a year.

Great video of your adventure! I recently moved to Portland and this is the best website I've found for the points of interest. Including an explanation on the rails you found www.geoffkirby.co.uk/Portland/700720/#Caves

[@Nigel_Broatch]

That's a good website. I've only just looked at it even though you posted your link a year ago! Good video too. I couldn't get the link to the first video to work though.

[@zerofox7347]

I wonder if the tracks were for a canon? Ideal spot for surprising ships during god only knows what war!

[@Nigel_Broatch]

Yes that's all I can think of too.

[@stephendickinson7071]

The passage was originally called railway dig, a trolly was used to haul waste back to the entrance. It is now called Allotment dig entrance and joins up with the rest of the cave, which is known as Grove cliff cave or flagpole cave.
