There has to be a (probably) grisly story behind the name of that promontory!

Basics, including Kite(3agi5,3h47)-3a7; UP36
[HP(36)gi5=3a5-3a9=(3-7)e9=(7-4)d9=(4-8)d4=8d5]-8gi5; UP81

1. Note a12c1=568;a46=17.Unique possibilities to 32.
2. Whether b8=5,ac5=25;OR b8=3,e8=4,d9=7,d26=25;d5=8.UP44.
3. f5=9 to avoid 39 unresolvable rectangle @ gh35.UP81.

Hi Alfred, nice solution; but UP81 instead of UP44 because of 9gi3-(9=4)h1 !
Best Regards, JC.

Your comment, Bev, led me to find out the story - nothing grisly: 'Govetts Leap was named after William Romaine Govett, an assistant surveyor in the Surveyor-General's Department of New South Wales. The name 'leap' is an old Scottish word meaning waterfall or cascade....'

I thought the same thing as Bev. Glad that there is a much better story behind the name. Joyce.

One of my favourite lookouts in the mountains. I was last there with Kathy and Jane.

Thanks JC.I saw the UR first (at UP32), and thought it was still necessary at UP44.
Best Regards, Alfred.

I missed h6=9, so should be 1. UP36, and no UR at all.

Kobold, as a pattern-illiterate solver, my breakfast must have been much more stimulating than I realised!!
