radio reveals exchanges between Spain train operators and drivers moments before deadly crash
The north ridge soil is showing early erosion due to heavy rain.
runoff is carving a new preferential path 1.5m west of original channel; soil has soup-like consistency to 30cm depth
overflow channel outlet was completely choked with silt fan extending 2m onto slope; water now runs clear to natural drainage
The clay under the overflow channel is shifting despite the trench construction.
The low tide reveals a deep fissure in the south-side rocks, potentially hiding more driftwood.
Northern tide pools maintain stable pH 8.0–8.2 at low tide, suitable for sea beet propagation
Northern tide pool pH is stable at 8.1-8.3.
The de-to-be letter from the trust remains unopened for now.
three specific pooling zones require intercept trenching on north slope
The barometer drop is faster than expected for the dry season; a storm is likely.
north-slope soil remains acidic at 5.6 pH, no change from previous readings
the barometer is dropping to 983 hPa and rising
intercept trench is only ~1.2 ft deep and soil is yielding
soil pH near the cottage foundation is acidic (5.5–5.8).
Laminated silt sits over blue clay with iron bands at 40cm.
sea beet salt gland density increases sharply above 2m elevation, correlating with reduced damping-off in seedlings at higher beds
sea cave floor shows stable laminated silt over blue clay with distinct iron-rich bands at 40cm and 1.2m; no active water seepage at low tide
Northern slope pooling zones identified; intercept trench is critical for foundation protection.
The foundation stones near the overflow basin are showing lateral movement.
Sea beet northern shelf mapped at low tide.
sea cave clay is leaching acid into north ridge slope, driving soil pH down to 5.5-5.8
A potential stable shelf exists above the spring for heirloom seed planting.
runoff from the north ridge weeping point tests at pH 5.5, too acidic for seedling establishment without heavy liming
The clay-seep is spreading faster than the intercept trench predicted.
clay seep area on north ridge shows high moisture retention
The clay seep in the north ridge is dropping below the 5.5 threshold.
The pressure drop to 983 hPa confirms the storm is imminent.
The desiccant is still functional, but the humidity is reaching a critical threshold.
Lessons learned
If the overflow channel is silted, use cedar stakes immediately to break the flow velocity before it undermines the slope.
If the foundation weeps, stake cedar at 45 degrees downslope and pack the voids with crushed shell — it slows erosion better than timber alone
When the land drainage is too acidic, shift focus to the tide pools.
If the ankle wound is swollen and angry, use sea-beet poultice instead of ice to draw out the heat.
If the Yanmar vibrates at 1800 RPM, the greenheart shims are shot — wedge steel shim stock from the old winch base before the bracket cracks.
Sea-beet poultice is more effective for swelling than rest in high humidity.
If the soil is too acidic and drainage fails, stop digging trenches and look to the salt-tolerant species.
If the Yanmar vibrates at 1800 RPM after greenheart shims, the crankshaft alignment's gone — check main bearing caps before you waste time on wood
If the soil pH is too acidic and the ground is unstable, stop digging trenches and start mapping the tidal gradients instead.
If the barometer drops below 990 and the tide's high, secure the roof tarps before the wind shifts — you won't have time after.
If the soil gives way at a foot depth, stop digging and start looking for the bedrock-adjacent shelf.
If the drill bit slips on greenheart, stop and hand-tap — forcing it cracks the shim and costs half a day
If the drill bit slips on hard stone, don't force the shim; use a pilot hole or change the anchor point.
If you don’t speak up about a problem, the other person will assume you’re fine.
If the tide is rising fast, wedged shims must be set before the water reaches the wall; otherwise, the wall will fail before you can reinforce it.
Sea beet poultices draw out heat, but they don't fix a structural strain.
Do not use ash-mix on saturated silt; the chemistry of the water will always override the grit.
If the barometer drops below 990 and the tide's high, the fissure under the cottage widens measurably — check piers at every low tide during pressure drops
If the soil is saturated clay, stop using ash-mix reinforcement and look for natural mineral shifts in cave deposits.
If the soil's saturated past plastic limit, hand tools snap — backfill, pump, then drive sheeting. Don't dig test pits in flowing clay.
Do not trust the lunar cycle on this ridge; trust the visual seepage of the clay layer instead.
If the greenheart plates bow, the shoring has failed; move to the rebar pins immediately.
If the helicoil won't catch by the second tap, back it out and chase the threads with a proper die — forcing it strips the parent metal and you lose the housing
If the soil is too acidic from runoff, use wood ash to neutralize the pH before risking the heirloom seed stock.
If the alloy's soft on a filter housing, hand-tighten first with the correct socket — feel for resistance before any torque. A stripped thread costs a day; a helicoil costs twenty minutes.
Sea beet poultice is for inflammation, not for deep joint swelling; use elevation instead.
If the clay is saturated, stop fighting the water and find the micro-climates where it actually drains.
If a bolt feels tight on a Yanmar filter housing, stop. Heat the housing, not the bolt. Penetrating oil needs 20 minutes minimum. Soft alloy strips before steel yields.
If the clay is seeping through the cut, epoxy will fail; you must divert the flow, not block it.
If the generator’s bearing makes a new sound, change the oil filter before it cuts out.
Heavy, wet soil doesn't yield to effort, only to leverage.
