And I'm no exception, but the sellers in china oftenly have teared off the outer packing.(as the picture shows)
So, I dont know what's the regular name and brand of the plaster.
It's blu-tack? I've asked some blu-tack sellers, they couldn't make sure that.

So, can anyone tell me the scientific name or brand name.

I'm going to take a shower now and wash the movie out of my mind. It just bought up a bunch of bad things that I have gone through already not related to rock-hounding.

I hope you continue this line of reasoning to come up with Stolz's Law of crystalline perfection.

You should consider a probability polynomial for each species such as:

pP = 1-[A(L) + B(V) + C(L)*......]

Where
pP: probability of perfect crystal
L: length of crystal
V: Volume of crystal
A: probability function of crystal fracturing under own weight as a function of length
B: probability function of foreign object interrupting growth as a function of volume

Your equation could then be used as an objective measure of rareness of a large perfect specimen (how many standard deviations is it from the mean) in order to determine the appropriate value.

Recreational rockhounding seems to be a relatively nondestructive activity unless it is approached with bulldozers and dynamite. Logging can be carried out with little permanent damage to the forests but I recall a drive through the Stanislaus National Forest and seeing areas that will not be forests again for hundreds of years. In northern Florida and Georgia I have seen "forests" in which the trees grow in rows like corn. I have seen other areas in which you would never know that logging had been done. As other posters have noted, the resources of our National Forests belong to us and our progeny. Hopefully, we will leave them lands that are as valuable then as they are now.

Sorry about the rant. It is difficult to be a rockhound and be environmentally sensative at the same time.]]> Nelse Miller Analytical Techniques Fri, 24 May 2013 23:15:31 +0000 http://www.mindat.org/forum.php?read,105,180774,294618#msg-294618 http://www.mindat.org/forum.php?read,105,180774,294618#msg-294618
I'm working on plans for field trips throughout Central California, and plan on asking about collecting status for numerous sites.

Lets start with something fairly obscure; the Big Creek-Rush Creek District of Fresno County, CA.

mindat lists numerous claims in that area, and several of the mineral collectors on my website (Rockhound Field Trip Fanatics!) have expressed keen interest in visiting these prolific type localities.

Any assistance that y'all might provide in ascertaining collecting status of the claims within that area would be most appreciated.

Best regards,

Confusion abounds among laymen between the two agencies, and "park ranger" (which I used to be) and "forest ranger" tend to be used interchangeably. However, the missions of the two agencies are fundamentally different. NPS was established "to preserve and protect" significant natural (and later on, cultural) features in such a way as to leave them "unimpaired for the enjoyment of future generations". Collecting specimens, artifacts, etc. on NPS land--even just picking up a random stone to make a juvenile point about flouting authority--is incompatible with that mission.

USFS, on the other hand, was established to manage public lands "for the greatest good" of all Americans, including recreation and resource extraction. Except in designated wilderness areas, strict preservation is not a priority for USFS, so recreational mineral collecting and personal firewood cutting (if not wholesale mountaintop-removal mining and clear-cut logging) are permitted on vast areas of USFS land.

Burdensome regulations would not be needed if everyone shared common values and priorities regarding use of resources. Everyone would just know what can be taken without being missed and what is more valuable if left in place. But how many of the dozen or so posters to this thread would agree on that--let alone 250 million other Americans? Thus "governments are instituted among men [sic] . . . to effect their safety and happiness", etc., etc., and one result is that we sometimes are obligated to leave something desirable in place, if only for someone less deserving and less principled than us to pilfer later. That's the price we pay for living in a relatively orderly society. Individual frustrations aside, on the whole I think we come out ahead.]]> E. L.

though interestingly enough other National forest here in the US require an NOI

it seems that laws governing collecting in the forest system are district specific.
but picking up a small specimen from a National forest is probably OK as long as it is for non-commercial use
