I agree with estimation of Mohawkite.
You'll know that both this and Bumblebee are toxic. Of course toxicity is dependent on exposure and this can / will have been reduced by taking the appropriate precautions. This post is intended for those that are not aware.
Beautiful cab btw!

Phoenix, with an Elevation of 1,086 ft (331 m), is the capital and most populous city of the U.S. state of Arizona. With 1,563,025 people (as of 2015), Phoenix is the sixth most populous city nationwide, the most populous state capital in the United States, and the only state capital with a population of more than one million residents Barnes Butte, AZ Barnes Butte is a Summit in Maricopa County, Arizona with an elevation of 515 meters, or 1,690 feet. Degrees Minutes Seconds: Latitude: 33-28'04'' N Longitude: 111-57'23'' W Decimal Degrees: Latitude: 33.467822 Longitude: -111.9562562 For Barnes Butte, 1690 - 1086 = 604 feet above surroundings. Considering that lot of ground level must have been washed away, that means floodwaters near 500 feet!I did a little armchair photography from Google Earth. 1. Barnes Butte and McDowell Butte (apparently = "Big Butte." I didn't know about "Little Butte.") There has been some erosion around the bases. McDowell is a quarter mile long (yellow line). 2. Street View of McDowell/Big Butte. Not taking away from your estimate of thickness (I haven't done one) but just bear in mind that the strata are dipping around 45 degrees (previous links have the specific no) so don't be too reliant on elevation above current sediment plains. Essentially, the buttes are the eroded edges of the strata as they jut up into the sky. ETA See Fig 2 page 2 here

Fantastic! I've been wanting to go there. Trip reports please, both of you! They have wifi so if their cell service is decent I'll post a thread and give updates. fantastic5, Ann who's your teacher? Do you think you'll be able to post while you are there? You know they give you a day to ROCKHOUND!! Now I'm starting to wonder if I can change my class to your dates since they may have spots available... what ya think? Busy times, both of you! Don't forget to pay attention in class and not be too busy updating your social media!

vegasjames - the nitro was a test to see if my heart / brain feedback was good. It wasn't... spectacularly. All good now. Yeah, I had slow sodium too.

Looks like the slurry is overdosing the plants as they get older. Root development accelerated. Leaves getting distorted. Overall stem growth is overly massive. Accentuated veins in leaves is often a sign of poison. Can be other causes. Suspicious of excess nutrient. Slurry on right. Root development better w/slurry. Stalks thicker. Slurry on right, occasional leaf distortion. 6 pots of slurry on left front corner, note curly growth. Plants in slurry blooming earlier and at a higher rate. I'd be interested to see the fine root development too. Given the nutrient uptake is from roots feeding on minerals abstracted from coarse-crumb soil, it makes sense that they find this easier from fines. I would expect fine root division if the plant finds the slurry is sharp on a microscopic scale. Or is it so fine that this is not the case?

Thanks. I have heard a late snowfall, a lifetime accomplishment for some areas of the country, fixes N. I wondered where it came from. The N, I know a thing or two about snow. I blame global warming ... Snow in Germany last week is supposed to be coming to the UK this week. Oh JOY!

I had coronary issues a few years ago and now wear (have inserted) a pacemaker. Luckily I'm now pretty bomb-proof... the doctor said I'd need to be run over twice with a JCB in order to kill me. I've only been run over once and it wasn't a JCB so I'm still kicking! The thing that struck me about heart issues is that there are so many different 'flavours' each with it's own peculiarities. What is good for one isn't good for the others. For example nitroglycerine (yeah you read that right) is used to lower blood pressure for folk with heart-attacks; for people with my issue, it lead to my heart stopping outright for 2.5 minutes. It even had the cardio team twitching. For high blood pressure / heart attack likelihood they recommend reducing salt intake. I was on 10g / day. The funniest thing ever, going to dinner with a friend who had a quadruple bi-pass - he said 'Do you want chips with your salt'. Had to be there I guess. Get fully checked, some answers and DYOR out before making any decisions on whether or how to treat / self-treat. Otherwise you might do yourself more harm than good.

mohs and metalsmith , last night I think I came up with an answer. A thousand year dust storm capable of carrying large rocks colliding with a thousand year rain storm = 10,000 year mud fall! Like a too thick icing on a cake, top drying out, too moist inside at less supported areas pouring out. Note the people at the bottom of 57 for dimensions! Well I don't think you're wide of the mark here; then again , in parts I think you are wide of the mark. Think of the force needed to lift the larger clasts (described elsewhere mohs as some being / approaching boulders. Just what would be required to make those babies fly? Alternatively mud flows are well known agent for transporting boulders. Youtube will help out by demonstrating present-day equivalents. I'm not sure how you have pegged these sediments as aeolian. The authoritative sources I've seen suggest these are debris flows resulting in breccia. Perhaps there are aeolian components? There are present-day equivalents for this: Meteorologically the chance of a 1000 yr rainstorm colliding with a 1000 year dust-storm is very low. Of course, assuming statistical independence the likelihood is a product of the independent variables, thereby 1/1,000,000 years. The chance of a 1/1,000,000 year combo happening is very close to 1 i.e. a certainty in only a 5,000,000 period of which there are many such 5ma periods over a geological epoch. However, what does a 1/1000 year storm look like? Well the relationship of increasing magnitude / reducing frequency (increasing rarity) is approximated closely by a log-scale. River flow can be generalised as doubling with a power-increase to the exponent, i.e. from 10 to 100 year rarity or from 100 to 1000. I don't know what your Q10 storms look like and you may even have seen a Q100; there's a roughly 1/5 chance of this occurring in a 100-year period. I'm not sure how the relationship stacks up for wind, but some severe amount of energy would be required to make the boulders take off. Aeolian deposits are forming in present day China, but the wind is generally not laden with rocks, even if dust-storms are noted. The flows that created this sediment were probably landslide, if dry, fluvial or alternatively submarine avalanches (I don't know enough about the setting). Either way they were highly energetic and turbulent. They will no doubt have been rare events. I don't think we need to consider aeolian influences as additional. If there are aeolian components, then reworking is the much-more-likely candidate for incorporating them. A rare (severe) storm event could be enough to form a debris flow and precipitate (pun intended) a breccia. Debris flow deposits are unlikely to include aeolian sediments outside of re-working. The reason for this stems from the meteorological difference between dry dust-laden air and moisture laden storms: a cushioning effect would be effectively pushing the dry dust air mass in front of the storm.

Wow!! now this is getting thick as the melted mud crust of the Papago's I like it Recall that I mentioned about the government land? No access! National armory? hhhhmmmmmm…… Unfortunately what buried at Barnes Butte in Phoenix is classified. Top secret! Even Petersen couldn’t get in to inspect the melt! Perhaps I’ll try…. Mercury

I ordered from them. Ordered a Genie DVD how-to, actually received it quickly but it must have been old because the disk was corrupt. I emailed them with my problem and they said Diamond Pacific was expecting more soon so.... not so great experience but not sure who's at fault. I'm contacting Diamond Pacific tomorrow. You should contact the people you did business with. Presuming you have paid them they really should have an obligation to complete the provision in order to satisfy the contract.

If this report is reliable,then Barnes Buttes is partially comprised of tuff, which is aeolian. However, it is different to loess by virtue of particle size, the effect of winnowing and the proximal source where loess can be remote. Also, through the semi-molten state of tuff ash-fall tends to lend to welding together of the particles so that the resulting rock is much more dense. I have some English tuff to hand. I can get a photo at the weekend.

metalsmith, I've also considered very heavy windstorms that convert to torrential rains. Would the torrential rains not serve to collapse the open macro-porous structure typical of loess and converting to flow, lead to the recognised fluvio-sedimentary features such as current ripples, dunes and lower and upper stage plane-beds? See bedforms phase diagram, fig 5-12 hereActually, I'd be interested to know what bedforms are present in loess.

Just a generic image, but this has to be one of my favourites: Uses: - Measurement & determining how much additional filing for metal / grinding for cabs
- Measuring how close I got by eye (generally ~0.1mm)
- Measuring the size of finished objects for listings
- Checking square / pythagoras
- Marking off metal - transferring lengths / effective diameters to strip
- Marking off metal - delineating parallel lines and (orthogonal) stone placements
- Useful for picking up small stones too! Just enough pressure to hold under tension.
Any more?

metalsmith, Great information! - But it does not account for the long capillary tubes, empty spaces, odd clay masses, nor the snails. What I like about the waterspout idea is water between the particles that later dried out accounts for the spaces. Air bubbles rising accounts for the tubes, mud balls slammed together in the wind accounts for the odd clay found. Oh, and also the snails. It does not account for the huge volume. 1dave you have a great mind for information. Consider then the volumes of sand in the Taklamakan, Mongolian Steppe and Tengger deserts. It is the winnowing of these sediments that produces loess in China that exceed 300m thick in places. Now that is volume indeed! Without source or observation I would suggest that the tubes are more likely to be accounted for by differential cementation by percolating soil-water than water-spouts. By what mechanism would the water-spouts defy gravity? In the UK, I'm aware that the brickearths are accompanied by calcite crystals; these would dissolve in carbonic acid (rain water+CO2) although what stimulates the precipitation, I'm not sure: there is an inverse temperature relationship with Calcite in solution (assuming temperature decreases with depth); perhaps saturation and ion-exchange with the clays is sufficient. I don't know if you have clarity on whether the snails are terrestrial or aquatic? As per my previous post, though, I suggest the snail shells are the result of alternative landscapes such as gully-fill or lacustrine (if aquatic) loess depositional areas or washed in by fluvial mechanisms. Do 'mud balls slammed together in the wind' have a modern equivalent / analogous environment? I wonder how pervasive these are or whether they are a local phenomenon? I would look to the local environment to explain the creation of the clay-balls in a local context before extrapolating it across the global loess deposit terrains.
