Perhaps you could take pix of your bog to show us?I now have two places that I have been working on, the Edwin Lakes area pond sinking spot which requires lots of working each spring and early summer to loosen it, and now the Crescent Road pond sinking spot, which doesn't need loosening, only building up to be exposed earlier in the season and also reshaped/widened to make solid ground even more out of reach when you are in the middle!
When it is thick, it is really fun to try and escape from! But first, I have to get a chance to get out there!
Believe it or not, I am still waiting for my first chance to sink! 
This has been one of my most frustrating seasons in a long time! Normally, I begin sinking in early April! While we were consistently warmer than normal from January to the end of March thanks to El Nino, with things looking quite promising, things turned around at the beginning of April (El Nino was dying out), with the weather being consistently cooler than normal, and cloudier, and unsettled! We did get the odd break to warmer weather, but each time it looked like things were looking up, we would get strong gusty winds, rain, and then colder weather again! The warm breaks, when we did get them, seemed out of sync with my ability to take advantage of them for sinking.
For the first one in late April, I couldn't take advantage of the heat because I had snapped a tendon in the end joint in my baby finger (fdp avulsion) in my right hand in late January removing a clump of dead brown leaves from a dormant crown of Lovage (large, celery-like herb) while cleaning up our raspberry patch, and had to wait 12 weeks after the surgery for it to heal completely before I could do unlimited activity. Naturally, the week of heat ended just when my limitations were eliminated! So, it was back to waiting for the cool unsettled weather to end. Then, in May, we had another warm break in the weather, but I got sick with the flu (probably picked it up in a restaurant on Mother's Day, but at least there was no nausea, only suffered from diarrhea, aches, soreness and weakness)! After I recovered, there was one warm day, but it fell on a Saturday, and I wasn't quite in shape for biking into the higher elevations (my dad wasn't available to give me a lift into the mountains that day), and I felt Harris Creek was a bit riskier, since people would be out motorbiking and atv'ing, and all they would have to do is leave the road, go across the adjacent small clearing to the clifftop, look down and to the right, and see me in the distance, doing my thing in the debris field! 
After more cool unsettled weather, just as another break was coming up, I got sick with a cold (might have picked it up at the hospital when I had a follow-up appointment with my surgeon)! After that, but still with a cough, another break came, but I was in the middle of a gardening emergency. I was propagating waterlilies in bathtubs outside, and the soil had expanded to the water surface, pushing some crowns up out of the water, threatening to dry them out in the heat. Once I had that fixed (removed the waterlilies, removed the water and half the muck, added clay soil to the remaining muck to make it heavier, loving working with the warm muck, re-added the water, and replanted the waterlilies), it became windy again, then cooler, and then more showers, and cool and unsettled.So, I am still waiting (still coughing a bit 18 days after first coming down with the cold), and I have a feeling that this may be the first year with no spring sinks, since summer is only a few days away.
But then, it could have been worse. 
To the east of the Rockies, the prairies have been hit with torrential rains again and again, which is bringing flooding that farmers haven't seen in decades! 
At least the rain we have here has been not too long lasting, not as heavy, and mostly only occasional showers. Our lack of snow over the winter months thanks to El Nino means that the water levels in the mountains are low to begin with, hopefully meaning more mud exposed this year!
