Simple subject, but beautiful color and composition, Kate!

It always amazes me how "things" can grow out of a rock! Thanks!

Great texture. Have a great day/night, everyone!

That's quite a meager existence those guys are eking out on that rock.

1) Start at 22,basic techniques to UP=31
2) (8=1)i5-d5=d7-(1=6)e8-g8=(6)i9,=>i8<>8
3) (8=25)f13-(5)f6=(5-1)e6=(1)g6-(1=8)i5,=>i1<>8
4) (5=8)i4-(8=1)i5-d5=d7-(1=6)e8-g8=(6-9)i9=(9)i3,=>i3<>5
5)(9)i3=i9-h8=c8-c4=(9-8)e4=i4-(8=1 )i5,=>i3<>1.UP=32
6)(5)i4=i1-e1=(5-1)e6=g6-(1=8)e5,=>i4<>5.UP=81

2)=>i9<>8

~20 minutes - I'm having a problem with the timer

Thanks Sotir, for questioning my faulty solution yesterday.I posted another attempt there today.

Could be a dinosaur grazing

1. Unique possibilities to 31.
2. If i9=9,a6=9=e4,g8=6,e8=1=d5,i5=8 and central box is devoid of 8.So i3=9 (UP32).
3. If d5=1,i5=8=e4,e6=9,f6=5.Likewise,d7=1,pairs 24 at d45;18 at ei5,locked 8s at ab6 makes f6=5.(UPs to 38).
4. If i5=1,e6=1,e8=6=i1 and top right box is devoid of 6.So i5=8.(UPs to 81).

Hi Sotir.I think you made a typo in step6).Shouldn't the last term be ...-(1=8)i5,=>i1<>5 ?

I feel like that sometimes. Like I'm hanging on to a cliff.

Another alternative:
1) Start at 22,basic techniques to UP=31
2) (8=1)i5-d5=d7-(1=6)e8-g8=(6)i9,=>i8<>8 (step 2 above)
3) (5=8)i4-(8=1)i5-d5=d7-(1=6)e8-g8=(6-9)i9=(9)i3,=>i3<>5 (step 4 above)
4)Loop:(9)e4=(9-1)e6=g6-(1=8)i5-ghi4=(8)e4),=>e4=89,e6=19.UP=81
