# Turn Back the Clocks

This is part 45 of the puzzle series Around the World in Many Days. Each part is solvable on its own.

Dear Puzzling,

This is a Slitherlink puzzle. Draw a single continuous loop along grid lines that does not cross itself. Numbers indicate how many sides of the numbered cell are used for the loop. Ignore the grey lines and letters when solving the Slitherlink – those form a background puzzle that helps you find the final answer in the end.

Today I have visited a uniquely beautiful aquatic ecosystem. Unfortunately I was not allowed to dive in, but that may be for the best from a conservation standpoint. Can you guess where I am?

Hints:

The clock shapes can rotate but not move. Only the ones matching the Slitherlink solution are relevant.

• It seems to me like the Penpa is not letting me mark edges as a line. It is only allowing me to mark crosses. Commented Dec 1, 2023 at 14:40
• @BenjaminWang I had the opposite problem but the solution is to click on "Tab", check composite, then click on "Composite" where it appears next to "Tab", and then click on "Loop" -> "Edge x" Commented Dec 1, 2023 at 14:45
• without a puzzle name, "gladys will return" sounds really ominous lol Commented Dec 4, 2023 at 17:00

Take the slitherlink solution as posted by 0x5453

and then

where possible rotate the circles to align the line segments with the slitherlink path. Thus the JEOL circle stays put, the YLAF rotates 270 degrees clockwise, the HSIP rotates 180 degrees, the AHNK does not rotate and the AEHL rotates 90 degrees.

Finally,

for those circles where the edges match we read off, from left to right, using only the letters within the slitherlink border to see JELLYFISH LAKE:
