Two days after my wedding I went caving in Fresnedo and we found a fair bit of new stuff, which we named appropriately. From the Matienzo website:
Just beyond the chamber is a 15m pitch and the start of The Honeymoon Series.
Traversing to the left at the pitch head (rope protection required) gains a high rift passage leading to A Bit On The Side, a 24m high aven. A 2m climb at the back of the aven leads to a traverse over loose boulders around the top of Oh Wow!! chamber some 7m below. This pops out onto a balcony looking back into A Bit On The Side about 6m up from the floor. At the top of A Bit On The Side there appears to be a very large passage and the rock here looks excellent for bolting.
The bottom of the 15m pitch is a large chamber, Trouble & Strife, from which there are two ways on. The first is to follow the obvious downstream passage, All Downhill From Here. This continues in a southerly direction through waist and then chest deep water until a final sump is reached in deep silt. This passage heads almost directly back under Howard's Way, some 15m above, and is presumed to be the upstream continuation of Howard's End. At the back of the sump pool, a mud bank leads to a boulder choke in a small chamber. There is a possible passage leading out of this chamber, but it would require some serious digging.
The other way on from Trouble & Strife is up a 3m pitch on its north side. This leads up a cobble slope in high passage and appears to end at a boulder choke. However, the way on is to climb onto a large, poised boulder from behind and then step off into a crawl at head-height over a drop. A second, more difficult, climb down is then met, but this can be bypassed via a wriggle between boulders on the left. A section of rift passage is then followed until a deep hole, Tying the Knot, is encountered (undescended, looks blind), with an in-situ traverse belayed to naturals. Water can be heard here and a large streamway, Honeymoon Period, is soon met.
Downstream is Holey Matrimony, a sloping, possibly slippery, climb of about 4m, which has yet to be descended. Upstream, the passage is as tall as 15m high and is liberally decorated with calcite and straws, with glorious white calcite lining the streambed. This fine passage continues for some distance, ascending a short climb and passing over several loose boulder piles. The first boulder pile appears to have a small side passage on the right, likely choked; the second has an aven with a small passage seen above; the third boulder pile has a large, draughting side passage, Extramarital Inlet, coming in from the right behind boulders (unentered). Continuing upstream past fine formations, the passage soon degenerates in size until a boulder choke, Hitting the Rocks, is met. A crawl at stream level leads into a very small continuing passage that becomes blocked with large boulders at Irreconcilable Breakdown.
A fine day's exploration which ended at a pitch. Others went back, the lead soon ended and was called 'Grounds for Divorce'...
