They are indeed Cave Myotis, not free-tailed bats. They probably moved into one 
of the other area caves now that the pups are volant. Roost switching like that 
is not at all uncommon.

Probably would not be freetails but Myotis velifer (cave myotis). We are on the

Re: [Texascavers] MOPAC extension meets "karst features"

[Geary Schindel]

Great post George and he is correct, geophysics isn't cheap or easy.

For those that are interested in seeing many of the different geophysical 
techniques demonstrated, you can attend the 6th Texas Hydro Geo Workshop to be 
held at Cave Without a Name in Boerne, Texas. Dates are Friday, October 4 
through Sunday, October 6. You can register on line at 
https://hydrogeoworkshop.org/  and also review last year's program to get an 
idea of what is offered. The workshop is set up with a series of approximately 
40 modules on various forms of field data collection and interpretation. We 
usually have more than 300 people attend the workshop from across the state and 
surrounding states.

In past years we've had experts in the field demonstrating Electrical 
Resistivity, Ground Penetrating Radar, and Natural Potential in addition to 
numerous borehole geophysical techniques. Other modules include stream gauging, 
water sample collection, field safety, introduction to caving, rock 
identification, aquatic biology, karst feature identification, tracer testing, 
cave geology, environmental drilling, and core analysis, etc.

Subject: Re: [Texascavers] MOPAC extension meets "karst features"

Microgravity is a great technique, but like everything has its pros and cons. 
The units themselves run in the $70,000-$90,000 range, depending on the model. 
Unlike resistivity and some other methods that give you measurements throughout 
the slice of earth you are studying, microgravity gives data for each point 
measured, which is then interpolated for the areas in between.

If you're looking for typical meter-diameter or smaller karst features found in 
the MOPAC area, you're talking about making measurements every meter if you 
want to maximize the chances of finding them. So if you're looking only at a 
100 m x 100 m area, and measuring a 1-m grid, that's 10,000 individual 
measurements. If the technician making the measurements is good and
very fast, you're looking at best at 1 measurement every 10 minutes, which 
totals nearly 17,000 hours, which at a typical consulting rate for a technician 
of $50/hour that's $85,000 just for the field work, which doesn't include data 
entry, processing, analysis, etc. to get the actual usable results--and the 
folks who will do that will charge substantially more.

I forgot to mention in my previous message that with geophysics you also often 
have to trade depth of study for the level of detail. Usually, if you are 
looking for small features you can't see deeply. If you look deep, you usually 
aren't seeing small features, only big ones. Sometimes two surveys are done by 
the same technique of the same area, one to look shallowly and one deeply.

To complicate matters further and add to the costs, all geophysical techniques 
have strengthens and weaknesses. I usually like to use microgravity and 
electrical resistivity together because they complement each other nicely. 
Where each is weak, the other is strong, so if you get a hit on both you have 
much higher confidence in your interpretation and in avoiding false positives 
and negatives.

No matter what system you choose, high costs and technical complications and 
limitations will keep the effort from being easy or cheap.

[Texascavers] sort-of barely Houston related

[David]

>From David Locklear
( not affiliated with any other character )

My lease on my apartment in Alief ends in 13 days.

In the apartment, I have only a plastic folding chair and plastic
folding-table and inflatable-mattress and an inflatable loveseat, and a
used 65 inch flat-screen tv.   All that junk, is going into my storage unit
next week, with all my other junk.

I have no idea whatsoever what happens after that.

My #1 goal in life at the moment, is to kick out my feminine Nigerian
Craigslist roommate.   He and I are not compatable roommates.   Imagine
that ?  I am worried that he will try to be a squatter, and ruin my plans
to evacuate.
So I invited him to share a seedy motel with me for 2 weeks after I move
out.  He declined.

If I were to get my deposit back from the slumlord, I might could get
another apartment.   But signing a lease again, would be so unpleasant.   I
am burned out and diminished from apartment shopping.

I can almost guarantee you that few jobs  as bad as mine does right
now.   I watched roofers spreading hot asphalt in the blazing sun, and that
obviously is a different kind of .

My spoiled daughter, Cavepearl, is giving me about 3 weeks to come up with
the funds for her quincenera party.   She is barely speaking to me, but
occasionally text an emoji.
Part of me does not want to go to it.  The party to me, feels like an
undesired deadline - like a final exam.


I am disappointed that I missed the recent caver gatherings near Austin or
in Austin.
