Water temperature - Yonaguni in January

[soldave]

I saw a few groups of hammerheads on our diving trip, and one one dive a whole fleet of about 80 of them swam under us - pretty impressive. Didn't manage to get too close to them though so good shots of the sharks were at a premium. I was satisfied with my shots of the ruins though. A few of my photos are up here:

No problems with my flight leaving, although the winds were strong. I had to leave a couple of days earlier than intended, but that was due to me being given incorrect transport information in Okinawa. I'll update my blog later with my Yonaguni stories, and some good picture explanations. Until then, you'll have to make do with my gallery

Just a heads-up to say that my blog has been updated with full details, photos, and even movie files of my diving trip to the underwater ruins. Let me know what you think if you get the chance, or if you've any questions about Yonaguni or diving there

Nice blog! I got to go down there last February (2006) and did a total of 5 dives - 1 on the monument, one at Danno Reef, two a hammer-way, and one at a different site (forgot the name - lots of swim throughs and impressive coral formations though).

After diving the monument, it is hard to imagine that it is anything but man-modified. I've never seen nature make such perfectly straight lines and regular shapes...

What hotel did you stay in down there?

I wanted to believe the underwater structure's were man-made.... but I came away thinking they are natural. My friend who accompanied me (coincidentally he is a geologist) also thought the same.

There are a lot of wierd rock formations in nature - the Giants Causeway, slate rocks also often fracture into large planar surfaces. Here are a few rock pictures I got from a quick Google
